"Stun Grenade" or "Flash Grenade" used by law enforcement. Combines a flash of light and a loud noise (imagine that) to startle, immobilize, or stun an enemy as the team makes entry.

It's also the grenade in CS that makes your screen go white for a full second. Desired use is associated with room clearing and pwning the other team, so why are my teammates the only ones who ever seem to use them on me?
I totally flashbanged my team and it won the game.

1. ) Sneaky maneuver derived from Call of Duty 4 (flashbang grenade).

Cum in a female's eyes and then swiftly smack her square in the ear. She will experience a flash of white followed by a ringing in the ears - similar to the effects of a flash bang grenade.

2.) pre-ejaculation

The devil woman's conniving tactic to (re)insert themselves into a man's life via sexual practice on a bro.

Dubbed flashbang because it is comparable to the disorienting nature of a flashbang grenade. One does not see or think clearly for a temporary amount of time after said flashbanging has resulted upon them.

This is often done by a "Ratchet" Ex-girlfriend who doesn't deserve to be with the said bro and shortly afterwords begins to weasel their way back into a comfortable status quo so they can suck all life from the target and all bros (and bras) of said target.
to flashbang :

"Dude, did you hear what happened with Randy and Galinda?"

"We've talked about this bro. Those two names are never to be mentioned in the same sentence."

"Dude, I know, but we have a code black."

"I've never even heard of code black."

"Dude. I know...She flashbanged him!"

"My god!...Whats the status?"

"Kill confirmed. That but fucking whore`s gottem.
