"Cheesy" (verb, defined by Webster's New International version): as in dumping on one or two, kicking the ball after losing a point, swearing, passing out dirty looks to your opponents and partner, playing the whole court on serve receive, serving continually to the weaker player, not slapping hands on side changes, thinking your opponents are throwing every ball they touch (even if they are), not congratulating opponents win or lose at the end of a match.
