You stand in a chalked on the floor circle, and you squirble by performing weird hand, head, neck, arm, leg movements to see who squirbles the best.
After determining who wins the squirble (Squirble can go indefinitely if nobody pulls out something that's extra ordinary and out does everyone) the winner starts the beef.
The winner chooses the fellow Squirbler to attack and does them dirty. The circle continues until the beefing is boring.
Yo lets go Squirble Beef tonight?
My grandma wanted to Squirble on this Beef.
