The act of repeatedly playing flip cup with a mobile table in the middle of the street in a circular manner around one's block after being angrily rejected from a back yard by one's neighbors. May include angry neighbors who fail to recognize the significance of depositing empty cans in said neighbor's mailboxes, and hurried dashes down major highways while carrying a table containing party cups, empty cans, and a rack of beer. May lead to arrest.
Dude, i can't believe we played block cup around your block after getting kicked out of the backyard by your old grumpy neighbors. That was the shit!
