V. When two or more persons are together, one person preforms a "Butt Chug" and the other party lowers him/herself to receive the alcoholic rectal discharge orally. Before preforming the "Thunder Gun" one person must proclaim "THUNDER GUN!!!!" very loudly to find a willing participant and the first person to scream " AAAAYOOOO" will be the honored recipient of said Thunder Gun
Ethan: Damn I'm thirsty
Joe: THUNDER GUN!!!!!
Zach: AAAAYOOOOO
......
Ethan: Damn I really wanted that thunder gun :(
