Broken Hearing Aid
When performing the act of coitus (fucking) the male pulls out before ejaculation, grabs his partner by the head and cums in his partner's ear canal. While the recipient is cleaning the semen out (as will be the inntial reaction) the male then punches them in the very same ear. The load of cum in the ear makes it hard to hear and the punch causes a ringing effect....hence "broken hearing aid" (I came up with it, but would never do it)
This girl I dragged home from the bar is a dirty little slut, and since I have virtually no respect for womankind or myself, I thought "hey, why not give her a 'broken hearing aid' to make her feel completely un-loved and worthless like pretty much all the other men have done in her life!"...so I did.
