"Détournement" is short for "Deadly Tournament." The letter 'e' also replaces the letter 'a' for a reason which nobody can explain.
Détournements occur frequently and many video games have been made concerning this subject.
Often in these deadly tournaments, fighters will engage in a battle in which THERE CAN BE NO WINNERS!
WHO WILL WIN?!
In "A User's Guide to Détournement," Guy Debord writes, "détournement is less effective the more it approaches a rational reply."
What he means is that these tournaments are always more KICKASS when it involves irrational, brainless killing. Hence, "Unreal Détournement" is a very popular example.
