PUGGLE is one of several Scots words that describes tiredness and fatigue, and it has many variations to describe being worn down in some way.
Trauchled, another word that conveys a similar state of weariness, can also encompass a feeling of being harassed or overwhelmed.
Puggled, however, can also convey the effects of tiredness, such as frustration, bafflement, or being on the verge of losing one’s patience.
Very occasionally, it is also used to describe a state of inebriation - perhaps because being puggled is also English military slang for being very drunk.
In most cases, the best cure for such a state - brought about by a hard day’s labour or a few too many jars in the pub - is a lie down on your scratcher. That’s your bed, by the way.
