A person's serial killer trait is something people will look back on for explanation in the event that they become a serial killer.
Person 1: Did I ever tell you that I brush my teeth with two hands?
Person 2: Ew, no that's so weird. That's your serial killer trait!

A person who comes off as creepy looking, weird, and a loner/psycho type because of their extreme paleness.

Someone whose pale skin and/or creepy smile makes you think Jeffrey Dahmer look a like.
That dude is all pale and loner looking, I bet you he is a serial killer, I guess that's why they call is "Serial Killer Pale".

See that Serial Killer Pale dude over there with the ROK initials on his bag/suitcase. I bet you those initials stand for like Real Original Killer.
