Damn girl, I'm beginning to sprout an Alfalfa
Why should I wash my filthy mouth out?
Alfalfa is a “sprout” (hence “sprout”) but also the name of a character on The Little Rascals, known for his foul mouth (like an early version of Eminem)
He might also be suggesting something since Alfalfa has that signature erect cowlick.
