A walking, talking puzzle, also known as a riddler or an extremely annoying question making machine. Also another term for shitting your pants and custom striping your underwear. A Gooonsch can be known to make you puke from time to time with its ungodly aroma of shit smells.
Did the baby just shit it's diaper? No, it was Goonsch.
