When you have the high ground in a tactical battle or in fact anything and you completely screw yourself by either self destruction or sacrificing your advantage.

Most frequently used in the star wars miniatures game x wing in which the definition came from. The player sets his ship dial to the course that they believe gains them a tactical edge. However due to their miscalculation the ship ends up flying off the board and fleeing.

"i cant believe you flew your ship straight off the playing field that is known as The Denvir Manoeuvre!"
"lol you just pulled a Denvir!"

"You had the most powerful ship in the match and in your first turn you did a Denvir!"
"careful now you may want to check your dial for TDM"
