A person that is shorter than the average male for his era and has an attitude because of his stunted growth. Any human male under 5'9" is classed as a 'short-
arse'. Only when they have the related attitude problem (otherwise known as 'short-man-syndrome') can they class themselves as a short-
arse-
twat.
Most short-arse-twats normally try to 'big up' their actions, have loud unbearable ringtones and pretend to know it all in a
bid to get themselves noticed.

Barry: "Yes he was"
Paul: "don't worry about it, the 'short arse
twat' would have been lying to impress you.
