look up any word, like hipster:
 
1.
A false cognate which, when spoken in Latin America or Spain means "how many," but in the United States refers to something equivalent in revulsion to a large, steaming pile of rotting dog feces.
"Oh, damn. I just stepped into a big steaming pile of quantas."

After sucking a fart from the bum's asshole, Ben exclaimed, "Ewwww, quantas!"
