A sexual act in which an individual, while performing oral sex, inserts her/his fist into the recipient's anus, thus simulating French horn playing.
Bill had a rough night after getting French horned by Mary; the next day he had to wear Depends as a precaution after all the stretching.

When a man tucks his penis and balls in between his legs so they stick out from under his ass and another person blows him while squeezing his balls as if they were trumpet valves. Preferably the giver's nose is nuzzled tightly between the receiver's ass cheeks.
I had swamp ass that day, so when Jake decided to give me a,"french horn," I hestated, then quickly said yes anyway.

The only non-percussion instrument in a classical orchestra that can be played with just one hand. It was invented to be like this because the horn player's other hand is usually otherwise occupied.
