Alright. But I didn't make it up, I'm only commandeering it.
Suckafish.
Not a command, as in, "Why don't you go suckafish!" An exclamation to be used, as in, "Aw suckafish, I totally just beat that level/killed that guy/etc." or a name to be called, as in, "Yo, suckafish, all your base are belong to us!!"
Stole it from Habboop.
