v. To take a monster shit.
Origins: Said and performed by hockey players immediately before a game so that they do not shit themselves when checked on the ice.
"Waterloo lost and was killed because he didn't pre-game dump. If he had, history would have been changed for EVER!"
The Pre-Game Dump is a relaxing experience which prepares you both mentally and physically for a stressful event. Although originally meant for athletic events, it can (and should be) used before any big event such as an interview, a speech, or an important exam.
Effects of the Pre-Game Dump include: Reduced stress, feeling of readiness, focus, and confidence.
One side advantage of the Pre-Game Dump is that it eliminates the chances that you will shit yourself in the specific stressful situation.
