It’s a hand grenade! Pretty poetic, don’t you think? I heard the term last week when a cop was discussing a series of incidents in Fukuoka Prefecture in which the trucks of a landscape gardening company had grenades tossed inside them while the drivers were away, none of which exploded.
It seems like a very evocative word for those little instruments of mass destruction. Of course, I probably seemed like an idiot asking, “Why would yakuza throw fruit inside a truck? Does a pineapple have some sort of cultural significance?”
Sometimes a pineapple is just a pineapple; sometimes, it’s a grenade.
