D: Yo, I swear after I get done with her, she wouldn't walk right for a year!

Get the Crutch Fuck mug.
When a guy is used by a girl to get over her previously failed relationship. A girl you most likely meet at a nightclub. Sexy and flirtatious but also carrying some baggage.
That bitch Amber was such a fuck crutch. After we fucked her ex threatened to kick my ass

I don't mind being a fuck crutch. At least I'm getting laid.

Man, that bitch wouldn't stop talking about her ex until I stuffed my dick in her mouth.
