1. The act of tagging a douchebag on the back of his shirt or his vehicle with an embarrassing sticker or label that clearly reads "Douchebag". This form of tagging is becoming more and more popular across the United States and is a anonymous way of letting a Douchebag know that they are infact, a Douchebag! Most douchebags are totally unaware of the fact that they act like douchebags and just need some enlightenment.
"Douchebag Tagging" is similar to the all time favorite game of taping a sign on someone's back that boldly states, "I'm Gay, Please Kick Me"!
