When you're drunk like a motherfucker, you feel you need to sneeze (what could go wrong, right?) but you end up barfing all over whoever/whatever you're facing.

A Bloomer is someone with a bright outlook on life who is optimistic in nature. Bloomer's frolic in every opportunity to be happy and try to make the most out of life. The opposite of a Bloomer is a Doomer. The term Bloomer originated specifically as a counter to the Doomer on sites especially like 4Chan.
