No! You have to drink every time he says “okay”!
Okay. 
sigh Kids today. So convoluted in their drinking games. What y’all need is a good game of “U-Chug”. Here’s how it works:
Everyone stands around with mugs of beer/shots. The first player points at another player and saus “You Chug”. That player does so, refills his mug, and then he points at another player and says “You Chug”. Repeat until everyone is unconsious. Elegant in it’s simplicity.
The Monk drinking game: Drink everytime Monk gets scared of something.
Monk: And/or when Sharona expresses annoyance.
To paraphrase Lynn’s old sig. Someday I will remember to turn uncheck my signature. Today is not that day. Sorry guys.
Didn’t anybody play quarters? You start with a keg, and the plastic cups they give you. Everybody sits at the table and you try to bounce a quarter off the table into the cup. If you miss, you chug the beer.
The Pokémon drinking game is a bit similar to the OP’s:
Drink whenever a word begins with “Poké-”
The opening of the TV show kills two beers pretty easilly and then all the Pokéballs and Pokécenters and Poképaloozas and whatnot…
The Titanic Drinking Game.
Drink whenever:
Cal is a bastard.
Someone swears.
Someone gets slapped. Drink twice if it’s Rose.
Jack and Rose kiss.
Rose changes her outfit.
Molly Brown defends Jack or Rose.
A person falls from the sinking ship into the water. Drink twice if a person falls and lands on the propellers on the way down.
The Titanic is described as “unsinkable.” On second thought, chug.
That’s all I can think of at the moment. I do know that it could be much, much worse.
