The act of hooking up with some
chick or dude. During the process of "Tearing it up", the chick,
or dude, gets so
fucking horny they ferociously rip, or gently slip, of their clothes and/or undergarments.(hopefully).
Example 1: Guy 1:Dude! Last night i got that chick so horny, we started
tearing it up!
Guy 2: She let you in on her
cuddy?
Guy 1: Hell yeah!
Example 2:
Girl 1: I was so wasted last night girl!
Girl 2: I heard you and that guy you met last night at the club were tearing it up at your
dorm!
Girl 1: Yeah, i hope he used a condom.
