momsectomy 

When you mother catches you having sex under age and cuts off your penis to prevent you from procreating.

I would love to have sex with you, unfortunately when I was 14 my mother caught me having sex and gave me a momsectomy. This is why i look like an action figure.

mansectomy 

A procedure for removing excess fat (man-boobs) from a male chest. Often used on old ex-bodybuilders whose chest muscles have atrophied to flab. (or possibly Phil Mickelson, he's got bigger boobs than my last girlfriend!)

The gender opposite of misterectomy.
misterectomy - When she finally divorces the bloke. A particularly difficult divorce from a very entangled relationship. A clean surgical break from a male spouse or partner from which the prognosis for recovery is improved functioning for her.
Judith finally underwent that desperately needed misterectomy. Too bad her HMO won't cover it.

Ole Billy Bob is drinking at the ice house tonight, he had a Msectomy in court today.
