Concussion Grenade

1.) An anti-personnel device that is designed to damage its target with explosive power alone.

2.) A type of fart where hopefully the Boom warns you before the Shock wave hits, usually resulting in holding one's breath and calling an O-ring repair doctor.

1.) "The perpetrator was neutralized by a concussion grenade."

2.) "Oops! Did u just hear that concussion grenade, quick plug your nose!!"

Russian Concussion

The Russian Concussion is when you are balls deep in a girl and smack her on the ear so hard that it starts to ring. Then, while she's holding her ear in pain, you cum inside her.

I was having sex with my girlfriend the other week and she told me to slap her, so I gave her a Russian Concussion.

Because of my concussion...

BOMC is an overused excuse that covers anything from simple blunders to awful failures. This phrase is used as an explanation for common shortcomings and can be used in most any situation. No matter what the occasion or what you did wrong, a concussion can always be blamed as the cause.

*In a small hospital room after a terrible accident while playing Cheerleader Chicken*

Cheerleader #1: Hey, how are you feeling?

Ashley: Abd oto ont. Teird tllite a. (Not too bad. A little tired.)

Cheerleader #1: I have no idea what you just said.

Ashley: Sorry I have dyslexia...Because of my concussion...
