Battle of appocalypse.
Attempt a 3sum with two guys and 1 girl.
Typically two guys are OGs and the female is an OL or OL referral.
Boa'ing involves anal into the girl and bj with the other guy same time. ATM is typically performed as well.
Guy are we going to boa tonight?
Dude I'm trying to, i have like 3 OL options, once I get confirmation I'll invite you to the lair.
