Callum

Callum is a type of guy who flirts with everyone even if its his ex girlfriend and is a big simp, callums are usually somewhat tall but not very tough so dont be alarmed, they are very nerdy on the inside but complete opposite on the outside. their way of flirting is very different to others which may seem odd but it works. They are sexy and definitely a keeper but very clingy. Once you guys are over he will be the last person to get over it.
Person one: ooooo hes hot

A Callum

A Callum is someone who is very smart academically yet lacks general common sense.

They tend to rarely have any thoughts and when a thought does occasionally come to the front they must announce it immediately. They often enjoy things such as fishing and talking about themselves in third person. An extreme case of Callumism would cause the person to call some women 'naughty girls.'

Being called a Callum could be thought to be an insult but is often quite an affectionate term used between friends.
