look up any word, like donkey punch:
 
1.
someone who dumps their trash in your dumpster, woods, or on the beach, or on your lawn
"My neighbor is such a trashole! He left his McDonalds crap all over my lawn!"

2.
Someone who litters; a litterbug. An asshole who litters.
Hey trashole, you dropped your beer bottle in my yard. Look at that trashole in the car ahead of us, he just threw a McDonald's bag out of his window. There are a lot of trasholes in our neighborhood, it's like no one's ever heard of a garbage can.
