gametime shower

a shower taken when you are about to be part of an important event such as a party, or when you are going to tackle a challenge. the shower is not done till you leave the bathroom

for the duration of the shower you may use your best soap, wash cloth, toothpaste, etc.

if you do not come out of the shower with your game face on, you did it wrong

possibly the best shower known to man
(don't forget to gaze into the mirror)
