Taken from the wise words of D Evil himself.
Means you're gay.
"I hear you have penchant for buggery?"
"No, I am not Gay"
To "randall" around would be to act out in an immature fashion. To be a "randall" would mean annoying those around you, and embarrassing yourself. "Randalling" around is frowned upon by most, with most cases of tomfoolery being reported to the police. Randalling is highly illegal in both Northern and Souther Korea.
"Will you stop randalling around! You're embarrassing yourself!"
