maclellan
A Scottish last name that belongs to someone with a pair of meaty tools that could beat up a whole family.
My cousin's name is Maclellan and his cock is so big it could launch a rocket.
I asked my uncle if he was a Maclellan and he said, 'I’m not, but I know a few who are.'
Maclellan is the only surname I’ve ever heard that makes me want to punch someone.
