A grade A douchebag who brags about his latest endeavor. Someone who likes getting attention and makes an ass of himself while getting it.

The act of extreme masturbation. You must "knock one out" whilst in close proximity to any of the following; Your mum, a nun, your boss, a member of parliament, George Michael. A person with capabilities to act upon catching you mid self-abuse obvisouly ups the ante. Ejaculation must be reached before your danger wank target comes (no pun intended) to investigate. The higher the chances of being discovered with one's pants down, pulling one's war face is obviously where the danger comes from. The more danger involved the harder (or softer) it is to complete the task in hand (snigger). The more dangerous the better. The chance of being arrested, pummeled by an angry father or having your hand severed by an arab's sabre means that you are a pro "Danger wanker."

both the act of boasting about douchey things (how may girls you have slept with, beers you drank, how you mistreated/condescended to a girl, etc.) and/or the douchey manner in which it is done (lack of consideration of volume or environment in which it takes place).

A male douchebag that brags about things not even worthy of bragging about.

That guy. The one that's always posting about his insanely awesome life. If you find one in real life, kill it immediately.

The art of posting photos or comments to social media, often using reverse psychology, in hopes of receiving validation for your false modesty.

A douchebag that will not shut up about their douchbagery.
