Sassy black dudes talking about Kolin

Mentioning Kolin's gigantic ass nose and Walking Dead extra eye color was straight-up merciless.
Drop this modded Kolin in a pool and it instantly changes colour.
You think Kolin, with her thicc ass nose bridge, is cute, so can we really take your opinion on beauty seriously?
It's just solid proof that Kolin is a mess.
The face that inspired Nash to go on a suicide mission.
Kolin's nose is more terrifying than any weapon in Mortal Kombat.
Kolin's nose is where Jews and the illuminati meet.
The rodent!!
