The Big Diesel

The sexual position of a heavier man and a skinny woman. The man puts his barrel (beer belly) on top of the woman’s butt and gives her back shots.

We did the Big Diesel last night. I could feel his barrel on my back, felt sooo good

Red Diesel

Normal diesel that is dyed red and for off road use only (so you pay no tax on it)

You’ll be able to run that on red diesel, just don’t get pulled!
