“the dude perfect”
is a move that u make while u jerk off
and almost shoot in ur face

u sit on ur coach, bed etc. and tilt ur head a bit forward so u can see ur penis.
if u almost gonna cum, u have to tilt ur pp half way so u can see the tip.
hold it in, and push it out
and like that. it will go like a rainbow to ur face

the whale tail is the shape formed when a g-string rides up high over a womans trousers

The act of having a hard-on and lying vertically in bed, while your partner attempts to throw a Glazed Krispy Kreme donut from the end of the bed on to your erect penis.
