S.I.M.P. 

An Initialism created by Phineas and Ferb in episode 35 of season 1, standing for "Squirrels In My Pants." If someone is dancing sporadically, they probably have squirrels in their pants.

"Yo, that girl has some sick moves!"
"Nah man, she just has squirrels in her pants."
"What a S.I.M.P., we just got served."
