When you're about to cum, aim for her eyes to blind your opponent then smack her in the back of the head and scream "Counter-Terrorists win!"
Example of "The Flashbang"
guy: pulls out and aims for her eyes
girl: "omg im blinded!"
guy: smacks her in the back of the head
guy: "counter-terrorists win!!!"

(Grenade, hand, stun). a less lethal grenade used by US police, as well as special forces the world over. Typically such grenades deliver 9 ear splittingly loud bangs and blinding flashes, which come half a second apart. These grenades stun and have a seriously immobilising effect. (From experience) your head seems uncapable of functioning, you cannot see strait (if at all) and you can hear nothing but ringing. The effects last a considerable time, and leave you with a banging headache. In a situation of use, such grenades would be tossed into a room to "prepare" them for a hostage rescue clearance.
a flashbang is tossed into the room.

B A N G !!!!!!!!!!!!!!!!!

Very very very loud, trust me! The occupants of the room are stunned and find themselves unable to do anything.

Then a four man assault team takes any terrorists prisoner or immobilises any firther threat before lining up the hostages for search and check.

"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.

when you get so drunk, high, or otherwise intoxicated that you can no longer see or understand what is going on. However, you are still able to get extremely lucky and sometimes score.
Dude, I was so flashbanged last night but I still scored with Emily.
