Big Chungus

Big Chungus is a meme involving a picture taken from the Looney Tunes cartoon Wabbit Twouble where the character Bugs Bunny appears overweight. It is usually presented as a PlayStation 4 game titled Big Chungus. It became notably popular on Reddit on December 2018.

Rips
In rips, Big Chungus is referenced usually from 1 of 3 songs: The earliest appearance of a Big Chungus song on SiIvaGunner is "Play a Mini-Game! (SECAM Version) - Mario Party" on April 12, 2019, which in this case was CG5's "Big Chungus".
 * "BIG CHUNGUS | Official Main Theme" by Endigo
 * "Big Chungus" by CG5
 * "Big Chungus" by The Slopster

CG5's and The Slopster's songs were featured in a few rips after that. Then, in late October 2019, the meme became a lot more prominent on the channel. There is also a  playlist, which holds an original arrangement.

Other references include the music of the original cartoon scene from where the frame is taken and a Billie Eilish parody by Tony Zaret.

In King for Another Day Tournament
Big Chungus appears as a character in the King for Another Day Tournament as a part of the Cool Meme Team.
