A biological theorem postulated by the famed naturalist Dr. I.B. Crunkdenstein which states that penile erection may be maintained during the act of intercourse with an ugly ass bitch if a paper bag is shoved on her head. Preferably, an orafice should be carved into the masticular region so that one may still scog down his partner's throat.
Yeah, so I drunk-fucked that Natalie chick last night--thank God for the paper bag theorem.
