When making out with a girl your dick is so hard for so long that when you are done you have left a bruise in the shape of your cock on her inner thigh.
"Hey man, did you guys do it last night?"
"Nah, but we made out for so long that I gave her a dick hickey."
"Pussy."
when a fat fukin chick thinks your cock is a nice juicy ballpark frank and sucks on it like she hasn't eaten in 5 whole minutes leaving bite or lipstick marks around your johnson.
