mudjumper 

A trashy, attention whore female. Who loves 4x4 ing with the guys and always comes back in a different guys truck. Often gives decent head (from practice). Known for quickies in the woods.

That Trisha she's a fun little mudjumper. If you have a good 4x4 she'll give you a ride for a ride. She might leave you on the trail for another ride though.
