Munro Sweat
Munro sweat is a highly potent date rape drug that has no effects on homsexual men, it is therefore often used to spike the drinks of hetrosexual men and boys, who are then used in perculiar sexual acts including but not limited to snowballing, figging, rusty trombones, and sodomisation.
