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.

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.
