When you are fucking a girl without using a condom, and come while your penis is still in her vagina.
Unusually cool.
She begged me not to come inside, but that only made me hornier and I came in her.
-Dude, I came inside this hot chick yesterday, and afterwards she tells me that she didn't take the pill!
-Ha ha ha, That will teach you to use a condom next time!
