something that is completely not up to regular standards. Something totally whack
Your mom has and awesome body, but her face is Whap whap.

Get the whap whap mug.
To unload a vicious right hook, left hook, and right uppercut in rhythm with the words in the song.
I was in a fight with some dudes and I heard Whap Whap Wow and I hit them with that Whap Whap Wow.
