Waa-waa
The sound a trombone with a mute makes. The trombone often being played by a man with sunglasses and a berret. Two consecutive notes in a row, the first being higher than the second. Only used when someone does something dumb.
"Hahaha, that fucker backed into the car! Waa-waa!" or "You blew bong juice all over your pants! Waa-waa!"
Get the Waa-waa mug.
