When you something bad happens and you automatically blame it on the nearest person with the name Tristan, even if they had nothing to do with it
Tristan was playing some volleyball with people and when a person missed it they all said, "Tristan, that was all your fault, you should have been there" causing a Tristan moment.

When a guy bearing the name of Tristan, unpromptedly and all of a sudden acts in a particular manner that is very much prone to result in the destruction of objects. Usually accompanied by heavy beatboxing or other ways of producing rythmical sounds.
Tobias : " Tristan, stop trying to put the LED into the socket!"

*LED explodes*

Pat: " This is such a Tristan Moment. "

*Tristan starts to shred it vocally-*
