Simp

(before 2020)

S.I.M.P. stands for "Squirrels In My Pants," a song from the show Phineas and Ferb in 2008.

In the episode "Comet Kermillian," the song was improvised when Candace was struggling to get two squirrels out of her pants. Immediately before, Suzy Johnson had used a croquet mallet to shoot an acorn into her pants and the squirrels followed the acorn.

So they wrote a song about entering a girl's pants trying to get a nut. And called the song SIMP. They are time travelers and no one can convince me otherwise.
