During sex when a man packs a fat lip of lady grizz (chewing tobacco) and is banging a girl from behind. When he approaches climax he starts making beeping noises like a truck in reverse, and proceeds to pull his bottom lip outward and tilting his head downward allowing the warm clump of chew to fall on the girls back.
1) Bro, i was hittin it from behind with a fat boy in and then i dump trucked a huge shwab of grizz wintergreen on her ass.

2) Dude, me and that chick banged at the party last night, but i didn't have time to take out my lipper so i had to dump truck her ass.

A loser. A lame fuck with nothing to live for.
Heather was drunk at the bar screaming about how nobody will ever love her and she will never have kids. What a dump truck.

If you see a good looking girl with a nice ass, plain and simple she is a "dump truck". Why? because you want this girl to come home with you and have her back it up and dump her booty on you. Meaning even more specifically intercourse using the doggy style position.
You: "DAMN DUDE!, check out Tracy!!!"
Friend: "Wow check her out, she's a dump truck!"
You: "I'm going to bring her home for some dump truck action tonight."
