"Onslows" are often seen wearing nike trainers two sizes two big, coupled with labelled grey jogging bottoms (adidas, nike, kangol are common brands) and a visior, from which gelled hair can be seen. Onslows often bop for no apparent reason. They also but on fake Watford style accents, favorite terms "owite?" "rightman?" etc.
