Grenade Whistle

Sometimes you're at the club and you bring a few girls home and you're a little cloudy so you don't realize you brought home grenades. So it's up to your roommate to blow on the Grenade Whistle to snap you out of it and bring you to your senses so you can kick that grenade out.

If you bring a girl home, and you are to drunk to realize she is a grenade. Your friends will sound the Grenade Whistle to let you know that your girl is a grenade!

Grenade Captain 

The guy in your platoon that is most likely to be selected to dive on the grenade while out scouting the enemy’s squadron. The Captain is most susceptible to volunteer or be called into active duty after his 9th plus beer or high ball and or sometime close to last call.

It’s almost last call, the Grenade Captain looks ready to volunteer, let see if he will dive on the nottie and save the platoon tonight?

We are all going to get knocked out if we can’t get the Grenade Captain to take the heavy weight 15 rounds.

the grenade 

The grenade is an alternative sexual manuaveur, it begins with the basic handjob. When the man begins to orgasm however is where the grenade differs because the one handjobbing makes a fist around the erect member and clamps their thumb over the penile orfice. This is usually followed by a yelp by the man because of building pressure and is usually released quickly with a explosion of white male secretion.

Me: Hey dude why are grabbing yourself?
Mike: My girl gave me the grenade because I called her Heather half way through.
Me: Shit thats some mean and cold hearted shit right there.
