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.

Callum-posting

The chronic habit of posting painfully mundane, oddly specific, and questionably profound WhatsApp statuses that nobody asked for—but now we all have to live with.

Often includes:
• Food hot takes that sound like rejected Dragon’s Den pitches

• Daily life updates that feel like side quests from a preschool teacher

• Music screenshots with cryptic captions that don’t make sense but sound like they might if you were high
• Off-brand motivational quotes with the emotional depth of a soggy Rich Tea biscuit
• Photos of countryside or suburban nothingness with captions like “Needed this”
“Man acts like he’s the main character in a Netflix indie short every time he posts. Stop the Callum-posting”

You know you’re Callum-posting when your status feels like a TED Talk but it’s just a tree and bad lighting.”

Callum core

A state of being in which you are fully enveloped into acting non-homosexual yet you are. Even if there are multiple sources which say you are you keep acting Callum core.
