The phrase one uses when intoxicated off butterscotch and Jagger-Bombs to break up make-out sessions.
Two people are making out, random fat guy comes between them placing one hand in the shape of a circle next to the other hand in a straight line and says with a lisp "Yo guy, sideways 90". Making the two people laugh and stop making-out, he is satisfied that he is no longer the third wheel.
