flugalhorn 

the beautiful musical melody performed by the suction of the mouth on the lips of the vagina. For a more acoustic version, the fingers can also be used.

Keep it on the Flugelhorn 

A phrase derived from the older phrase "Keep it on the DL". It was discovered in 2009 by scientist Ted Davis after a T9 error suggested flugelhorn instead of DL.

Ted: Hey, I think I caused Jon and Krysta to break up. But keep that on the DL.
Jack: Keep it on the Flugelhorn? OK, My lips are sealed.

flugelhorn 

A trumpet-like instrument which has the same valve combinations and is played in the same way but produces a deeper sound with better tone.

Corroded Flugelhorn

Similar to the Rusty Trombone, but this not-so-distant cousin adds the glory of unwiped "mouthpiece" to the equation.

She thought she was just playing the ol' rusty trombone, but due to Keith's lack of hygiene, it ended up being a corroded flugelhorn.

flugelhorn 

A perverse sexual act wherein the man inserts his fingers (or hand if possible) into the womans vagina, and proceeds to move it around in a way to make flatulent noises similar to those created when cuffing one's armpit.

Man, Kevin played the flugelhorn on that slut so loud last night that I could hear it from the room next door.
