Hydrocopter 

When you're all wet and you use helicopter dick as a method of drying yourself

"Sam, why are you crying?"
"Because Paul thought it'd be funny to throw out a hydrocopter and that water got in my mouth!"

harrocopter 

coined by 1 < a z e of Infantry Online to refer to clueless kiddie n00bs flying their helicopters as they are about to be shot down.

a variation of roflcopter and a literal combination of "harro" (leet chinese man saying hello) and "helicopter" to either mean "harro i am shooting you down helicopter" or "harro i am on a helicopter and you aren't touching me"

Oh, that harrocopter killed me.
So I was flying my harrocopter in circles around four lines of kids.
Lure that kid on his harrocopter here plz. Kthx.
Rorororor, you wish you can touch my harrocopter, son.
Harrocopter!
