A term used for when someone does something stupid or generally acts in a retarded manner.

Originates from the film Team America where a puppet of the actor Matt Damon is portrayed as stupid and slow, saying the words 'Maatt Daamon' in a voice that collaborates with this.


Example:

- guy falls down the last two stairs when meeting his girlfriend's parents for the first time -

'Scott get up, you're such a matt damon'

kids say 'matt damon' instead to saying 'god dammit' when they're around adults cause it kind of sounds similar.

When you do, think or say something stupid, that was clearly avoidable.

A usage example:
