The same gesture as the famous High
five but a more

sound like a high-fiving douche bag.
"So these frat boys in their Lexus' tried racing me in my VW, and I totally let them
blow past just to watch the cops pull them over... Up
Five!"
in lieu of an after-sex high
five: "YEAH! I just banged the shit out of you! Up Five!"
