Flashing Off

To show off. Behaving in a way that draws attention to yourself, or to make yourself look good in order to boost your ego.

Look at that guy flashing off his new overpriced Red Monkey jeans. He even kept the price tag on his pants. What a dick!

flash block

v. Manually placing opaque paper, such as an envelope, over an abnoxious flashing advertising banner--so that it is easier to concentrate on signing into a social networking site (using a complicated password), or to concentrate on writing a gripping response to an intense incoming message, for instance.

"Gotta flash block that trailer or I'll never get in!"
