You've gotten plastered for Star Trek, you've gotten wrecked sipping every time
Capt. Picard adjusted his shirt, and now you've got yet another excuse to drink
beer: the "Deep Space 9" drinking game. Like the ST and ST:TNG games, a drink
is taken for common events that are part of the show (such as Kirk always
kissing the (alien) girl, Worf getting beat up, etc). Some fans start to look
forward to these events. Just so I don't get blamed for somebody spewing, it's
recommended that you use shots or small gulps of beer when you take a drink.
You may want to have some harder stuff for special events mentioned below, or
chug a whole beer as suggested.

Before the show starts, everyone picks a character. Everytime the character you
picked gets into a confrontation, conflict, or fight, take a drink.

Plus take a drink whenever:

-something isn't working properly on the station -anyone says 'DS9' as the
name of the space station -violence breaks out on the promenade ring -the
wormhole is shown/opens (this includes the opening credits) -the station
is shown from outside -the 'cog' airlocks are used/operated -any door is
seen opened manually (if it's a 'cog', take two) -somebody mentions Bjor
(only one drink per line; any number during the scene) -Sisko threatens
somebody -someone hits on Dax -Odo is puzzled by humanoid behavior -the
Cardasian spy uses clothing as a euphemism for something else -Dr. Bashir
suggests something patently unwise

And then take a drink AND do an action everytime:

-someone rides the elevator to/from the control room action: say "going
up?" or "going down?" -a shuttlecraft is shown action: guess the name of
the craft out loud -Odo shapeshifts action: say "Jell-O!" -O'Brien uses
the transporters action: nostalgic sigh -Jake Sisko gets in trouble
action: say "Kids these days!" -Kira has a case of divided loyalties
action: put a drink in each hand and have a drink from both -Quark is seen
behind the bar action: take a second drink, or have a shot of something
stronger

Plus, chug a whole beer when and if:

-someone from Star Trek: The Next Generation makes an appearance (members
of the O'Brien family don't count, but secondary characters and extras
_if_ you can identify them _absolutely_ do count) -Sisko backs down or
knuckles under to someone else -Odo does something intentionally humorous
-Dr. Bashir does something clever not related to medicine. -Dax gets into
an amorous (sexual) encounter -O'Brien is asked to jury-rig something to
save the day and it doesn't work -Quark does something selfless

An average one hour episode consumes three beers per participant.
