Character: big floppa
Big Floppa is the humorous nickname and name of a meme based on someone's pet caracal named Gregory. They call him Big Floppa because in the original photo, he takes the stance of lying down, as if he'd just flopped on his side. He is a somewhat overweight caracal, which also contributes to the meme's humor and how "floppy" he looks on his side, like a pancake.
The caracal is owned by Instagram user prozhony, but memes often depict any caracal as Big Floppa, should a caracal be featured in the meme.
The meme came out at around the same time as another meme about a cat with a silly name, Bingus, so they have often been featured in the same meme together as dynamic duos, in a relationship, being different teams, or enemies.
