Person 1 "I fucking hate that douche-bag..."
Smarter Person 2 (probably a Myles) "Don't be so mean to douche-bags, that guy is in actuality, a fucking kevKevy!"
Person 1 "Do you see that homo over there licking that ice cream cone like it's a dick?"
Person 2 "That guy is no homo sir. You can tell by his dick face and general aura of worthlessness that he's truly a kevKevy... And I hear he can't spell either."
