Curie's doorknob

A sexual act in which a (preferably mildly to moderately radioactive) rod is inserted into the anus and rotated.

Yeah, me & my chick went out to Marie Curie's house a while back, and she let me turn her Curie's doorknob, if you know what I'm saying!

Bronze Doorknob

When A man Crams his arm into the vagina until it exits the anus covered in waste. Next the woman will grab his fist and rotate his arm inside of her loins for sexual gratification.

Last Night Laura and I tried our hand at a Bronze Doorknob. Needless to say, being a woman, she was all "sensitive" about it; and said she couldn't handle it....whata wuss.

during sex, you lube up your fist, aim, and upper cut your partner in the ass almost hard enough to fist them. the partner will scream and grab the closest thing to them, mainly the doorknob out of the house.
