Rules are as follows
1. Materials required:
a. one 40 oz. beer per person. (wine bottles may be used as a substitute, but not 12oz. beers. the drink must be in a glass container, and must be the height of a 40oz. bottle.)
b. a couple of U.S. quarters. (one is required, but often gets lost, so additional quarters on stand-by speed up gameplay. spare quarters are usually kept underneath savvy players' 40oz. bottles)
c. a pair of dark sunglasses (referred to as buttface glasses) or other vision-impairing eyewear (e.g. tinted ski masks or stunna shades etc.)
d. three or more players (preferably eight, or however many will fit comfortably around the table.)
e. a large table (preferably round, so that every player can reach across, although irregularly shaped tables can also be used. this will be discussed later)
f. (optional) loud, upbeat music.
a. Every player stands around the table and opens their 40oz.
b. A player (typically the host) will begin the game by spinning a quarter on the table and then calling out another players name. (this player will be referred to as the spinner).
c. The player whose name is called by the spinner will then attempt to clink another player's 40oz. bottle by smacking, hitting or flicking the quarter towards another player. (this player will be referred to as the flicker)
d. As soon as the spinner calls the name of the flicker, all players (excluding the flicker) will defend their 40oz. bottle.
(i) in defending your 40oz. you must keep one hand on top of the bottle, covering the opening.
(ii) your (other) defensive hand must slide up and down on the 40oz. maintaining contact with the bottle. (you cannot reach out into the table-area to smack away the quarter).
e. if the flicker successfully clinks another player's 40oz.:
(i) then the player whose 40oz. was clinked has become buttface, and must wear the buttface glasses.
(ii) position of spinner moves clockwise.
(iii) everybody drinks.
f. if the flicker did not hit anybody's 40oz. (their target successfully -and legally- defended their 40oz.) then the quarter goes back to the spinner. repeat step d.
a. "buttface-spinner" if it so happens that the person who becomes spinner has just become buttface, (the player to their right was the spinner on the previous turn) then everybody drinks twice.
b. If a spinner spins 7 consecutive turns and none of the flickers are successful in clinking other players 40oz. bottles, the spinner becomes buttface (see 2.e).
c. If the player who is buttface (see 2.e) has their 40oz. clinked 7 times in a row (i.e. if they suck at defending their 40oz.) then they are required to take a lap around the block in the nude.
d. If a player needs to leave the table for any reason, they must call "out," and leave their 40oz. on the table.
