Sometimes when you're really desperate (and usually drunk), you wake up next to a really fat chick with a face like a mangy dog. Whether you brown bagged it or not, the rumor that you slept with her has the possibility of spreading the second she leave's your room. Keep a plastic bag in your night stand for these special occasions. Just whip out that bag before the beast wakes, throw it over her face, and put that fat tub of shit down for good. Proceed to get rid of the body, as it might be evidence that you porked the porker.
The boys at the Frat house can never find out that I slept with Tina the fat lard, I better Plastic Bag this fat bitch.

To point your finger at someone and bare false witness against them. Plastic can be fake, not real, untrue. Humans often point a finger at someone when ratting them out and lying at the same time.
I knew that Mary was lying about Fred when she falsely accused him of the theft, she pointed her “plastic finger” at him and totally lied.
