In social situations, a short ball can be most loosely defined as anything that causes annoyance, discomfort, or rejection.
Sometimes, when saying "Shortball!', people use an accompanying hand action as if to fend the ball away from their chin, similar to a batsman in cricket. Experienced shortballers sometimes only perform the hand action without saying the word, or just abbreviate the phrase to "Short!"
