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!
