swedish hand grenade 

Ejaculating into a condom then tying off the end after removing said semen filled condom from the penis. The tied off condom then becomes a projectile used in urban warfare, usually thrown overhand at approaching enemy forces.

I was pounding out this chick but then her boyfriend showed up. I had to use a "Swedish Hand Grenade" just to escape.
