The Pre-Game Dump: Traditionally invented by athletes who would use this strategy to become more relaxed before an important game, the Pre-Game Dump is the shit you take before a big moment or event which requires high performance and low stress/tension for success.
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.
