The phenomenon that, no matter how good something is, if you mix it with something bad for long enough, you'll eventually
associate it negatively.
Derived from how great
air freshener smells in the store, but by the time you've used it to cover up 20 odd poops in the bathroom, you'll forever associate the smell
with poop and will hate it.
Example:
Jane: Hey Laura, where are them fantastic shoes you bought a few months back?
Laura: Yeah they succumbed to the Bathroom Air Freshener Phenomenom. I wore them round
Stu's house too many times. Now when I look at them they look sad and pathetic, so I dumped them when I dumped him.

Her: Didn't you used to like
Love Actually?
Him: Yeah but after watching The Walking Dead 3 seasons too long, I now can't look at
Andrew Lincoln without hearing that goddam accent.
