The Postal Dude is the protagonist of the Postal series by Running With Scissors, which began in 1997 and became best known for the open world sequel Postal 2 in 2003. His bored, deadpan voice lines were widely clipped and shared on forums, YouTube edits and soundboards because a single word could sum up an entire disaster. This short swear survived as a standalone reaction separate from the games themselves, reused whenever creators need an instant, low effort expression of frustration, disbelief or things going wrong very quickly.
