1. The act of grabbing & bending the visor, or 'peak' portion of a baseball cap someone is wearing the wrong way, as if bending a duck's bill, upward, while yelling: 'FURNGG' into their face for added annoyance.

2. What is yelled when grabbing & bending the visor portion of a baseball cap someone is wearing the wrong way.
<Frank (with an evil grin, & hand outstretched) approaches Bill, who is wearing his brand-new Yankee cap.>

Bill: Don't even think about it, Frank! This is my new Yankee hat I just bought at the new Yankee Stadium, and I don't want it ruined!

Frank: OK, OK, no problem, bud. (Frank begins to turn & walk away, but then suddenly turns back, and violently grabs the visor part of Bill's new Yankee cap.)

Bill: HEYYY!!!! DON'T!!!!

Frank: FURNNG!!!!
