bawjaws is a scottish term of (mild) abuse. Not as harsh as eejit, more like a numpty or heid-the-baw. I chose it as a username because I remember my dad calling me it as a bairn.
It must be falling out of use because even google only returns 14 instances of the word and a few of those are my use of it as a username. Maybe there's an alternative spelling. Anyway, one of the results gives a fairly good example of it's use in a play...
SCENE 1: ACTION REPLAY
GREEN'S CINEMA, RUTHERGLEN CROSS, AND SALAMANCA P.O.W. CAMP, JULY 1937.
MARY COLLINS, USHERETTE IN THE CINEMA, shining light into camera, then pull back into the action in the cinema. Show government newreel of events in Sapain, then the workers' cinema version replaces it. English minister stating why they are abandoning Cataluña - financial interests - Spanish stating they did the same in 1712.

At end of scene, focus in on newsreel, reaction shot of Mary thinking she sees her son, cut to real action.
