Two or more people dropping a pile of steaming two-flush corn-logs onto a willing (or alternately unwilling) participant. This act is like an amalgamation of bukkake and the cleaveland steamer.
"Dude, do you remember dump trucking on that homeless dude last night?"
"That chick at the truck stop was just begging for a dump trucking, good thing I ate that tuna sandwich!"
"Don't forget to eat some corn on the cob for lunch, today; Heather wants us to dump truck on her tonight."

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."
