Similar to a pick-up line but much more to the point. The sole purpose is to hook-up (have sex).
-That shirt is very becoming of you... and if I were on you I'd be cumming too.
-Nice legs, which hours are they open?
-(Use index finger to call someone over then say) I made you come with one finger, imagine what I could do with the rest.
Hot dayumm that was a good hook-up line!
