A completly unemotional sexual act done for the sole reason that it feels good. This can range from making out to sex and everything in between. You do not call hook ups back at a a later time and ask to go on a date, and ususally they are spontaneouse, so dont call back looking for more action either.
I was hitting on this hot lifeguard and she took me into the pump room and blew me, it was a great hook up.

Hooking up has come to define sexual relationships for most of today's teens and young women. It can mean anything from kissing and touching to oral sex or intercourse. Vagueness is its hallmark. "A girl can say, 'I hooked up with so-and-so,' and no one knows what she did. It protects you and makes you a player at the same time," -Aparicio (Sophomore at Boston University)
