rusty dump truck 

a girl one might fuck for purely utilitarian reasons. i.e. fat and nasty, but willing.

Scott rationalized sleeping with that Rusty Dump Truck the other night because let's face it, it was late and he hadn't been laid in like a year. There was also Jägermeister involved.

Mega Dump 

A dump so powerful that one feels the need to yell out "MEGA DUMP" as it's coming out. Frequently is an out of water experience, resulting in a dry docked dump.

Dude, did you hear Sean lay out a MEGA DUMP a few minutes ago? He clogged the toilet with just shit, not even any toilet paper. That guy needs to modify his fiber intake.

Pittsburgh Dump Truck

The woman lays on her back while you start shitting on her torso. Next, you proceed to scoot backwards to her face while saying, "beep beep beep" until you finally rest your ass hole on her mouth. This act should only be reserved for holidays or anniversary's.

"Susie will be pleasantly surprised that in her stocking this Christmas is a gift certificate for one free Pittsburgh Dump Truck."

Pretend to be in love in order to fuck a chick, and then dump her right away! Don't TELL her, just DISAPPEAR!
