A woman often found pleasuring the tramps of Bonn Square in Oxford. Shameless in her pursuit of 'tramp jizz' there is not depth to which she will not sink. Often found dogflapping two tramps at the same time.
She could suck a golfball through a hosepipe, like STFCBird trying to get more tramp jizz.
The act of pleasuring two men at the same time, without either of them knowing about the other. Simply put, the woman kneels within a large dogflap (like a catflap in a door, only larger), and men 'take' her from either end, without being able to see each other.
I was out in Oxford last week, and saw STFCBird dogflapping two tramps in Argos, near Bonn Square.
