also refered to as "shlocking," is the act of throwing Slurpees, or other forms of slush drinks, at pedestrians from the inside of a moving vehicle. While the origins of this activity are heavily disputed, the south shore of Suffolk County, Long Island has been known to be a hotbed for this unfortunately hilarious action.
Widely accepted best practices include the use of 7-11's convenient 4 drink cardboard carrier. Small slurpees are said to be the superior size for sloshing, as they easiest to throw and less likely to come apart prior to impact. Hotspots for such activity include movie theatre lines, high school house parties, college campuses, and retirement communities.
"I was super pissed that I wasnt included as a pallbearer, so I took off that stupid frisbee hat, hit up 7-11, and positioned Marty's dumb family at the wrong end of a gnarly sloshing session as they left the synagogue.
