Sex for its own sake; when one or both of its participants doesn't want or doesn't know if they want a committed relationship but are horny. Usually, sex early on, especially on the first date, is the hallmark sign of a hook-up.
Dude 1: How'd your Tinder date go last night?
Dude 2: Pretty good. We got dinner and drinks and went back to my place.
Dude 1: Nice! Did you hook-up?
Dude 2: Yeah, dude. She was pretty hot.

Yanks use 'hook up' differently to the rest of the English-speaking world. They use it in a sexual context or providing an item for somebody that's usually dodgy. Everyone else uses it in the context of meeting someone.
Hook up:
1) I hooked up with him in New York. We made love all night!
2) Hey! Hook a brother up with some dope!
3) I hooked up with my mate in London. I hadn't seen him in years.
