Cover art for Flies On My Dick lyrics by Ween

I think this is about him having a girlfriend who smokes weed(gypsy) but wont fuck(nun) and hes talking about not being able to have sex(flies on my dick)

or its about heroin

Hmmm, he's afraid he'll have to beat off because she won't give up the snizz? Actually, that kind of makes sense in a cracked Ween way...
