To have sexual intercourse with a person from a sovereign nation, recognized by the United Nations, thus laying claim to that person’s “flag.”

(v) The act of pulling another person's pants down.

The bandana one group or gang will wear/rock/display to let others know who they run with.

A bandana worn in the left rear pocket of the pants. These are usually worn by gangstas, rappers, and people who are influenced by rap music. I've only seen blue and white flags, although I'm sure there's red flags too (maybe even other colors as well). The white flag can be seen in Eminem's music video, 'Just Lose it', and the blue flag can be seen in Snoop Dogg's music video, 'Drop it Like it's Hot'. Snoop Dogg says that his blue flag signifies that he is a crip, so it seems reasonable that a blood would wear a red one. If anyone wants to correct me, then feel free to do so.

Skaters can also be seen wearing flags. They usually wear black or white ones (although the color probably doesn't matter for them), and theirs is neatly folded into a triangular shape and only about four inches of it stick out, whereas the gangsta/rapper/rap-influenced person practically lets the whole thing hang out.

A verb used mostly in the military to describe the act of allowing the muzzle of your weapon to cross paths with friendlies.

when one takes a book into the bathroom while taking a shit and reads it (ex: that one episode of Seinfield)

to avoid something.
