The Dirty scuba is when you get a really fat chick with an extremly beat up pussy, Stick your head all the way into the puss with a straw hanging out of your mouth. The straw acts an a breathing apperattis, another reqiurment is that you have to drink a Coors Light through the straw while your head is still inside of the fat broad.
i dirty scuba'd this girl last night and her snatch was nasty! The beer was good though.
