slam-bang

At a signal from Horko's box there was an all-out, slam-bang, grand salute of the guns and with it a pounding of the deep liquid bass drums.

"If you had led the rough, tough, slam-bang, every-man-for-himself life I have, you wouldn't be frightened of gorillas...."

"I'm a real, slam-bang, honest-to-goodness, three-fisted humdinger. I'm a bona fide supraman."
