jackwhack

Part jackoff and part whackoff.

Anyone that is being a jackoff that is doing something the equivalent of whacking off.

There's a guy in a tiger outfit drinking coffee and reading. We sit next to him and I look at him and say "grrrrrr".
He looks back with a blank stare like he has no idea what I'm talking about, then he realizes he's dressed like a tiger, and takes off his tiger ears and goes back to reading.

That guy was such a "jackwhack"
