Looking for the right word...

Hello and thank you for taking the time to help me.

I'm not even sure how to properly ask this question, but I'm look for a noun that characterizes in a general sense, when a person is acting like a stereotype or stereotypical character without using a specific label. It can be a metaphor as long as it's a thoughtful one (like using the term "lemming" to describe one who blindly follows without thinking).

For example: a white American male dressed in dirty, blue jeans, unshaven, Budweiser baseball cap, farmer's tan, big wad of chewing tobacco, drives an old pickup truck, lives in a trailer park, tells racist jokes, has a nasty girlfriend/wife, dirty, unkempt children...you get the picture. In this case, the specific label might be "redneck", "white trash" etcetera.

The word should be general enough to use in most situations where a person genuinely appears to fit a negative stereotype of a culture/race/religion/demographic.

Thank you in advance,
Mark
