Rusty French Horn 

It's a take-off of the rusty trombone, where you 'toss the salad', but instead of the handjob, you insert your fingers like you're playing a french horn.

"Yeah, I played her like a rusty french horn!"

Blue French Horn 

The act of ruining a perfectly good TV show with a terrible "twist" during the series finale; referring to the eyeroll-inducing "twist" during the series finale of How I Met Your Mother, where the entire story of how Ted met his children's mother turned out to be an unconscious attempt to ask his children if he can date his ex-girlfriend Robin again. Ted then shows up at Robin's house with the blue horn from their first date/the first episode.

"Man, I used to love that show, but the series finale was such a blue french horn."
"I can't believe how they blue french horned the TV show like that!"
"Remember when that entire season of Roseanne was just a hallucination? What a blue french horn!"
"They thought they were bringing the show back full circle, but really they just blue french horned the entire thing."

sloppy bavarian french horn 

when a female,(or a male), performs onto another male, an act in which from the rear position one hand grasps the rod of their partner and squeezes at different intervels(like tapping the many buttons on a french horn) all the while blowing, with a little spit, into the rear of thier partner to the tune of "Oh When the Saints Cum Marching In"

Nathanial readied himself against the kitchen sink while preparing to require a "sloppy bavarian french horn" from his fiancee Campbell all the while maintaining the beat of "Oh When The Saints Cum Marching In" with the slapping of his ball sack.

rusty french horn 

the woman is lying on top of the man with buttox and vagina exposed and elevated. the man places left hand around womans leg, reaching clitoris with fingers, and stimulating thereafter. with right hand, he inserts however many fingers are necessary to reach maximum pleasure, while simultaneously rimming her anus. (ex. female version of the rusty trombone)

Bill gave me a rusty french horn, but I had some dingleberries that obstructed the air passage, so his tone was heavily affected.

frosty french horn 

to consume whipped cream out of a naked human's bunghole; a sweeter, more refined, elegant, calorie-providing cousin of the rusty trombone

Kenny: "So the boyfriend and I finally took things to the next level last night...tooted the frosty french horn all night and went through 10 Reddi-whip cans!"
Asher: "You mean there's something tighter than the ol' rusty trombone??"
Kenny: "Oh man you have not lived until you've added whipped cream to the mix!"
Asher: "Looks like Friday night is finally gonna feel alright!"

Tooting your French horn 

The act of preforming oral sex on yourself by pulling both of your legs over your head. Contorting your body into the shape of a French horn with your feet being the mouthpiece and your head being the bell of the horn.

"Did you hear about Jeff trying to "Tooting your French horn?!"
"Yeah, I always knew he was lonely, but damn..."
