Callum is a great guy to be friends with. He's nicknamed 'small' but is actually small. Overall you should be lucky to be friends with him as he will be your friend forever. He's also a sweaty boi.
Me: Honestly I'm really lucky to have met Callum
Long lank: Ikr he's such a nice kid

The slowest human being ever. You ask him to play PUBG with you and he’ll tell you a long ass story before getting on. One word to define a Callum, spiky hair.
“He has spiky hair!”

“Must be a Callum.”
