michael: did you hear jimmy brag all day about his sexcapades with his slutty gf?
neal : due, i swear to god, if i have to listen to that douchenbaggen open his mouth again, i will literally beat his face in.
When a douchebag proudly brags about his douchebaggery (his douchebag behavior). This results in high-fives and/or "likes" from fellow douchebags, and makes everyone else shake their heads in disgust.

This is what you call someone, who is a known or obvious douchebag, that is currently bragging about being a douchebag, or bragging about doing douchy things. It will be very obvious.
