showing your dick

Similiar in meaning to the phrase "showing your ass", which according to Urban Dictionary def.#2 is "making yourself look like a jackass or an asshole, being a dick. embarrassing yourself or the people you are with in public or in front of other people, usually by doing something socially unacceptable. exposing your true colors in a negative way. also, having a nasty attitude in a public setting." However, the difference is "actually being an asshole, actually being a dick, not being embarassed by that fact despite it being socially unacceptable, exposing your true colors in a bluntly truthful way; appropriately lacking tact where tact is not warranted; calling out shit like it is".
