If you are a little pudgy, your gut may sag down when doing push ups or copulating. This can be particularly unattractive as during vigorous sex, it may swing from side to side, back and forth, much like a metronome. In extreme cases, the folds of fat, or female breasts, may slap together making a sound not dissimilar to the sound of a sealion performing for food at shows at many zoos. This noise is known as flap or tat slapping.
"Dude, I was fucking Cindy in the ass"
"Awesome dude! How was it?"
"Great, but her undercarriage was swinging around, almost knocked me off balance"
"Eww. Sick dude"

To pretty much run someone down with your car and quickly drive over them, they come in from the front and exit out the rear, essentially giving them a tour of the underside of your car.
"He was talking all that shit at the club so when I caught him outside in my Taurus I gave him a tour of the undercarriage"
