Lookout for Grenades.

On the TV show the male characters describe distasteful females as "Grenades". They have a large red horn that they sound off when one of the guys comes home with an ugly girl, or the Female characters come home with friends who are considered ugly. Someone blows the grenade whistle, or the girls are called grenades and all in all its really derogatory towards women in general. I’m sure females watching the show appreciate how these guys treat women, like trash. The girls on the show probably don’t enjoy being treated this way either. That brings me to my next observation, how to woman stay around people that act that way, you’ve got this man treating you with no respect and insulting you and most of the time they still sleep with them or still hang around them, Its ridiculous. Our youths watch a television show where it glorifies being a slob and acting like an asshole, and the sad part is they get paid for it. Kids probably feel like these people are living the good life, when this would probably never happen unless you were famous like these people, once their 15 minutes of fame is up, it won’t matter what happens to them nobody will care but at the moment these eight people are some of our youths biggest role models and they act like Neanderthals. It also shows girls to be inferior, like if they see men bullying them during their life time, they will never learn to stick up for their selves or earn self respect either. Every time I hear someone say “Grenade” and they are referring to a female, my eyes twitch because I realize how disgusting and derogatory it really is."Hey Mike, its like the grenade's flow to you like a magnet" - Pauly D
