You don't prank a full-fledged bro when you're still climbing ranks. That's some dumb shit to do, especially with no pledges around to use and abuse. Doesn't he know what horny frat guys are like? When the bro he pranked told the house what this bitch did, they all came down to teach his ass a lesson... and what a nice ass it is. Maybe knock him back down to pledge level since he can take dick so well.
