The act of trying to pick up girls when out on the town.
Used because the act of talking to unknown females more often than not looks like you are trying to sell them raffle tickets. Also the chances of taking one of them home are about the same as winning said raffle.
Dunco:"Man, I saw you sellin tickets last night! How'd you go?"
Red:"No winners man"
The act of behaving like an idiot when out on the town. Comes from a cross between grenade and radiation, as people who do this tend to have the effect of exploding through a club like a grenade and radiating annoyance through the crowd.
Dunco:"How was Mick last night?"
Ello:"No good, it was total grenadiation, he got us kicked out in ten minutes"
