Cuck has two definitions, both which people associate with Greg, although it is usually the first one. The first, and the original definition, is a man with an unfaithful wife. The newer and political definition is "demasculated Millennial liberal male who often speaks of white privilege and modern feminism." * (More info in "Notes")
The first time people started associating the word "cuck" with Greg was in late 2015 when he released his second book This Is Why I Hate You. In the book, the character based on Greg, Arthur, would watch his bisexual girlfriend engage in sexual activity with her lesbian girlfriend. Some people began speculating this was a fantasy of Greg's because that year he announced he allows his bisexual wife to date women. (Source)
Soon, Facebook meme pages that were directing people to spam Greg's social media with "Creamy Meme Dude" began spamming Greg with variations of the word cuck. (Source)
In January 2016, Greg began going into detail in videos about his relationship issues with his wife and her girlfriend. He also made two prank follow up videos faking more relationship drama. This series of videos went viral and as a result, calling Greg a "cuck" became very popular.
Greg has had mixed reactions to people calling him a cuck. Sometimes he says he is proud to be called a cuck because he supports his wife's sexuality. (Source) While other times he seems to be annoyed by it and tries to explain to people that he is not a cuck because he would never allow his wife to have sex with another man. (Source) He also explains his wife is not unfaithful because she only dates women he approves of. (Source)
Greg has also made two videos about being called a cuck. The first was "Is Onision A Cuck? (Is Lainey Cheating?)", uploaded to his Speaks channel on December 30, 2015. In the video, Greg explains to viewers he cannot be a cuck because his wife is not unfaithful. ($ource)
The other video was an UhOhBro video called "Why People Think Onision Is A Cuck", which was uploaded on June 18, 2016. In the video, Greg explains (in the third person) that people call him a cuck because he fits the political definition and he is in fact a cuck. ($ource)
Later that month, Greg posted a text rant in a video about how he realized people don't call him a cuck because his political views. He explains these people are wrong because he does not watch his wife engage in sexual activity, he participates. He says he had multiple "amazing" threesomes with two "awesome" people. (Source) He was most likely talking about Lainey and Billie.

On August 2, 2016, Greg uploaded "PLEASE, I NEED YOUR HELP" to his Speaks channel. In the video, Greg explains he was pissed off because a YouTuber named SniperWolf called him a cuck in a video. He says he is not mad at her because she was mad at him after he made fun of her posture in pictures on twitter. Before that he says they talked on twitter "plenty", but she immediately unfollowed him after he made fun of her.
Greg says people started calling him a "cuck" after he uploaded a video on December 12, 2015 of Lainey and Billie kissing. He, for the millionth time that year, explains he doesn't fit the "man with an unfaithful wife" definition because he gave his wife permission to kiss another woman. Greg says after this video was uploaded, in May and June 2016 new definitions began appearing on Urban Dictionary that all describe him. Greg says the top definition "sounds exactly like someone that dislikes Onision describing Onision". He reads: "A demasculated Millennial liberal male who often speaks of white privilege and modern feminism. Blames white men for all the world's problems. There goes Chad again with the megaphone telling everyone that he's a vegan, what a cuck." He says there were only two parts that did not fit him. The first is that he is not a millennial, but he says people assume he is younger then he really is. The second is that he is a vegetarian not a vegan, but many people mistake him for being vegan.
Greg reads a portion of the third most popular Urgan Dictionary definition: "Short for cuckservative. The word cuck is most commonly used to describe anti-white whites." Greg explains people think he is anti-white because of his support of the Black Lives Matter movement and his opinions on white privilege. He says they also describe on Urban Dictionary that "individuals like me" go after people that appear to be homophobic or racist.
Greg dictates to his followers a definition of the word cuck that he created about himself to post on Urban Dictionary and to thumbs it up to make it the most popular definition. He says to beat out the most popular definition, they would need over 2,000 thumbs up. He says if you like or hate him, making this definition popular could be a good thing. He goes through the five stages of grief and says at first he denied being a cuck, then got mad. He says he never bargained or got depressed over it, but now he is accepting it. ($ource)
The Cuck page on Urban Dictionary was flooded with spam of Greg's definition. By the next day, it reached the most popular definition with over 4,000 thumbs up. ([ Source])
Fans had mixed reactions to this video. Some thought it was fun and participated in the spam, while others expressed they thought it was an immature reaction to trolls.
- This definition evolved from the word "cuckservative" which originally had been used online slur to describe a conservative that follows liberal values. It became a mainstream political term in July 2015. (Source) Online, the term began to include other political parties as well and the new meaning became: "thinks he’s promoting his own interests but really isn’t", which would fit the modern liberal definition of cuck that people sometimes associate with Greg.
- Greg is a millennial.
