French Doorknob 

An acrobatic sexual act, achieved by a gentleman inserting his testicles and scrotum into a lady's vagina and having her simultaneously perform oral sex on him.

"...but Sarah, she was dirty as hell. Gave me a French Doorknob on our first night together. Anyway, will the jury please deliver its verdict?"

French Doorknob 

When a man packs both his penis and testicles entirely in a woman's vagina simultaneously.

Likely performed by the rest of the world ever since Adam did it to Eve, the French were the first to claim responsibility and ownership of the French Doorknob.

When you insert your balls into a woman's vaginal opening whilst she performs fellatio upon your phallic organ. Requires years of yoga training.

Chris: Dude, I hooked up with some chick last night, got a french door knob from her.

Misha: Dude! She had a mustache!
