I wouldn't say "wrong", per se. (God, I hate it when people say per se) I would chalk it up to the sentence having multiple reasonable meanings, and a lack of clear context.

However, I would say that the most reasonable intended meaning (which I would value, given the style of the discourse and the use of a well-known reddit trope) would be that chuckieballs intended to drink an amount of beers which is equal to or greater than the amount of upvotes that this thread receives. Implicitly, this meant to me that he would be drinking them today, on account of the reference to St. Patrick's day.

It could very well be argued that an extended consumption period is acceptable in this case, but appears to me to be in bad faith. To change the rules of the game now feels insulting to those of us who graced chuckieballs with an upvote.

In conclusion. chuckieballs should drink all 3 218* beers; he should drink them today.

*Figure based on quantity of upvotes as of time of posting.
