sidewalk pizza 

Vomit in the street (or sidewalk, as the name suggests)

I had a few too many Budweisers and on the way home cooked up some sidewalk pizza on main street.

Sidewalk-Pizza 

A large puddle of vomit that drunks upchuck on the sidewalk as they stagger toward their vehicles for all to enjoy! It often includes large chunks of smelly multicolored bits of partially eaten food mixed in with their puke!

Hey watch out for that Sidewalk-Pizza, you don't want to step in that puke or you will stink up the car!
