Back and bad as ever
like a bat out of hell
mad as hell
sing a song of frickin' sixpence, i don't know where that "at" came from at all. It just came out that way.
This is the state when you've just wakened from some rut or stupor, and realize that you kick ass. Oh, i forgot! well, no more..
don't push me man, i'm back and bat at as hell!
