An afternoon gathering place for boys in the early stages of masturbation exploration, in which they could sit and toss off save in the knowledge that girls rarely went to Wangas. Wangas was a big plot of wasteland near our school, and the tree a big, slightly collapsed Oak. If you sat in the tree you had to wank to the point of ejaculation otherwise you couldn't get down. The tree had an established hierarchy, the better you were at wanking, the higher in the tree you wanked. Therefore, you were less likely to be hit by anything flying out above you. One kid (Steven McIntyre) was really popular in our class, thanks to his hard Army brother, but fell down the wanking order after he claimed to have spunked, when in actuality he had just secreted a mixture of piss and precum. Dirty liar.
