bananus 

The little brown part at the bottom of a banana that no one in their right mind eats.

Only monkeys eat the bananus.

Bananus 

Making a bet involving shoving a banana up your ass and losing but following through on that promise nonetheless.

May 25,2021 u/Rick_Of_Spades made a bet on r/Superstonk that if GME closed above $200 he would shove a banana up his ass🍌🍑.

GME closed above $200 and he delivered on his promise shoving a banana into his bananus.

Bananus 

The little hole in the bottom of the banana when its pulled intact from the peel.

I like all parts of a banana, but probably my favorite part is the bananus.
