Downstairs French 

When you perform cunnilingus on a lovely lady. Maybe she's not so lovely. You do what you want with whom you want.

What do you say you put on that beret and put my baguette in your mouth while I go downstairs French. Don't worry about being all Marcel Marceau. My mom won't be home for another half hour.

downstairs breakfast in bed

The act of waking your partner with sex in the morning. Complementary to upstairs breakfast in bed, and typically gifted to a man. Borderline rape, so consider yourself warned.

What a beautiful goodpussy day it is; my girlfriend woke me with downstairs breakfast in bed that finished off with upstairs breakfast in bed.

Downstairs Beard 

A veritable mane of unruly pubic hair, often, nay, always accompanied by a massive overgrowth of ferocious facial hair. May be inhabited by various species of wildlife including: crabs, sabertooth crotch crickets, lice, fleas, small feral cats and the mythical crabacus. The downstairs beard, if left unchecked, will grow together with the upstairs beard creating one mammoth superbeard which will then slowly begin to digest it's host creature and become a sentient being.

Dude 1: "Dude! Why do you keep scratching your nuts? Knock it off!"
Dude 2: "Sorry, I've got something crawling around in my downstairs beard!"
