Men called Olly almost ALWAYS shop at Topman or at least River Island, wear really skinny Chinos, wear shit pumps that expose the hair on the top of their feet, wear beanies and wear very tight shirts that expose their non-existent six packs. Sometimes they may also pierce both their ears and wear extremely obvious large diamond stud earrings.
People called Olly will typically read the NME and worship indie bands such as the Arctic Monkeys. They may also take keen interest in The X Factor. They may also have an iPhone and Instagram absolutely EVERYTHING... typically hash-tagging all their photos.
They also have the most arrogant personalities. Olly will be very full of himself, thinking he can get almost any girl he wants by any means necessary.
All in all, if you are called Olly, be prepared to be labelled with these stereotypes. Whilst not all people called Olly are like this, they will possibly fulfil at least one of these stereotypes.
