The Blerm is a contraction of the terms "blumpkin" and "perm", and is used to denote a sexual act where a male receives oral sex in a toilet ("blumpkin") and then wipes his semen (or feces, if there is no toilet paper) on his sexual partner's hair upon completion of the sexual act. It is a common practice in certain bars in Conowingo, MD.
Man, that bitch sucked me off real nice in the toilet and then I turned her blumpkin into a blerm. That shitter needs more TP, by the way.
