Shortened version of "Havaianas Junkie" pertaining to a PERSON who is ga-ga over Havaianas: a brand of Brazilian-made rubber slippers, and owns several dozen pairs, even if these are considered quite pricey.
Note: Not to be mistaken for "havs," which is the shortened version of the brand itself.
"Check out the new havs of that group of Havies over there... nice!"
"Hey, Havie, have you seen the new releases of havs?"
