Hooking up is not necessarily having sex. However, It can span from making out to having sex
“We hooked up last night”
“Did you fuck?”
“No, hooking up doesn’t mean we fucked. We just made out and dry humped”
Did you see that Toad's hook up he just pulled? It was awesome
One your ex man is with another bitch
"Double double the hook up"
*picture with another bitch*
