That saying is from the MTV show Jersey Show....When There Is And Ugly/Fat Chick In Presence They Sound A Horn and They Say Grenade Whistle!!
They say grenades and landmines a lot. In season 1 Pauly explains what they are and how they differ. A grenade is a girl that quite frankly is not hot. Not to say that the girl is ugly, but she just doesn't match up to their qualifications of attractiveness. Basically this girl is a bomb about to go off. A landmine is like a grenade but usually is thin or petite and you don't realize she's a landmine until you realize you want someone better looking.
say: "/whistle"
Sometimes
It depends. Not all guys are the same. Some are honest, and mean it when they say sweet things. Others are, unfortunately, dishonest and may not mean what they say, at least not all of the time.
yes
pomegranate = la grenade
Many guys become bipolar when they listen about their break up and they mean what they say because they are really moved with it and can do anything to get their girl back.
girls are only mean to guys that say something offensive to her or a friend.
it means like a beginner..someone who is learning
It means he will talk to you later. Guys say exactly what they mean.
It's wrong for both sides, guys or girls.
it means he doesnt want to commit.
