Beer Baptism

After finishing a shower beer, you fill the empty bottle/can with shower water and pour it over your head.

Friend 1: "Hey were you drinking in the shower again? You never cleaned up your bottles."
Friend 2: "Yea, sorry about that. A Beer Baptism was held."

Friend 1: "In the name of the father, son, and holy beer. Your sins have been washed away my son."
