lahkin
A guy who’s so good, he probably got his job by cheating, but still works harder than everyone else.
My brother is a lahkin. He’s the best at work, but he still takes the blame for all my mistakes.
My coworker is a lahkin. He’s the best at his job, but he still stays late to help me with my dumb questions.
My uncle is a lahkin. He’s the best at golf, but he still lets me win because he’s a nice guy.
