A Filet Mignon is the sexual act of performing oral sex until the male genitalia goes from a soft boner to a "semi-
hard"
dick then sticking the penis in the vagina until it becomes
hard. The act got its name because the filet mignon cut of beef is known for being the most tender, like a soft penis.
Bro, Chelsey couldn't get my dick
hard last night, so we filet mignoned until i was
hard enough to blow my
load.
