n. when unreasonable feelings, opinions, or attitudes, esp. of a hostile nature, regarding a racial, religious, or national group, become the best way to describe someone.
i.e.- the subject fulfills the stereotype.
Tom- Holy shit, who the hell just cut us off?
Dick- Idk, she was Asian.
Tom- Ah, of course!
Dick- I'm sorry, dude, I'm not being racist, this is just a functional prejudice, no offense to offend.
