Calvin, known also as LeafyIsHere, LeafyIsBeefy, xxYungReptilianxx, Meme Lord, Beef Cakes or Hiss Guy to some of his fanbase is an American youtuber who mostly make videos of gameplay from Counter Strike: Global Offensive (CS:GO) overlapped with Leafy talking about various topics and ends with Leafy promising to give an assortment of obscure items (such as a speedboat or a potato) to viewers who like his videos.

Leafy's fanbase, calling themself "Reptillians" or "The reptillian brotherhood" are known to often spam on videos with comments like "HISS", mostly on videos that he talks about. Multiple youtubers and even the infamous hacker group "Lizard Squad" (known for hacking PSN and Xbox Live multiple times) once tweeted to Leafy with "hissing" multiple times, with the hissing becoming a small meme for his fanbase.

In January of 2016, Leafy video uploaded a video called "THE SADDEST MAN ON YOUTUBE", where he talked about the youtuber known as "MrBlackDarkness666", a depressed man who always got harassed by other people, including smaller children, where the man would tell the children to kill themself. MrBlackDarkness666 saw it as harassment and uploaded a video titled "LEAFYISHERE GO FUCK YOURSELF", in which he stated that MrBlackDarkness666's significant other left him because she thought that Leafy's video had a point and that MBD had to grow up, which ended up in an argument and his girlfriend leaving him. MBD666 ended the video with him showing a picture of Leafy in real life, setting fire to it with his cigarette and ripping it apart, claiming that he can make Leafy "go away." Leafy responded with another video named "SADDEST MAN ON THE INTERNET," in which he claimed it was not a video for harassment and that he was sorry for him, but that it's not Leafy's fault that MBD666's girlfriend left him.
