phut

Looks like this ol' sausage was punctured bad, an' I'm gettin' to think she's goin' to phut out quick an' go down wallop.

It was Jimmy whose ear first got the sound which came in—the feverish phut-phut of the motor skiff.

With the phut of the closing safety-valve came the conductor's cry of "All aboard!"

One moment he's gallivantin' about in beauty and majesty, an' the next—phut!

A bullet went "phut" into the ground at my feet as I lay on a stretcher.
