Acronym for You Have to Burn the Rope. Originated from the flash internet
game of the same title. It was purposefully created to be an absurdly simple game to
beat, with the description "
Computer games are getting so hard these days...".
YHTBTR can be used in reference to the game itself, or as a way of poking fun at someone who cannot figure out a very easy puzzle or complete a simple task in a video game.
