Inserting your finger into the end of a banana will produce a bananus, from which you can split the banana into three even sections.
Be gentle sticking your finger in the bananus or you may cause a tear.

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.
