Flash Grenade

When a Female squirts into a Male's mouth, then the male quickly spits it onto the Female's face, giving her a grenade-like splatter all over her.

We had an amazing time at the party last night! Some girl and I had sex, and I ended up giving her an unexpected Flash Grenade.

Flash Party

A social gathering on an "off night" of the week, usually at a bar or someone's house/apt, that starts out small but suddenly, unintentionally, and randomly reaches critical mass and turns into drunken mayhem.

"Last night McHugh and I went to the pub to have a few beers, but then people randomly started showing up and it turned into a flash party. Some Excedrin would be good about now."

flash in the pants

I had a flash in the pants from thinking about the night before, but realized I can't let it interrupt my work.

flash word

A word of the day that is popular for 15 minutes, and then everyone loses interest.

When that flash word first appeared it got many votes, now it lost it's #1 rating because no one is voting for it.
