A loud, all-purpose onomatopoeic exclamation commonly used to simulate the sound of a violent attack on a friend or loved one. In use, the word often deadens the desired effect of the threatened physical attack, resulting in derisive laughter in the victim (gooshee).
"I made a joke earlier about how Kirk will get his Social Security payments before he gets laid, and he gooshed me!"
