A popular phrase coined in the 2009 blockbuster The Hangover when the trio stole a police vehicle and realized that Stu had married a stripper in which they had several photos, mugs, hats, etc. of the event and "torching the cop car" was suggested as a plan of action to get rid of the evidence. This term is defined as disposing of, destroying, and/or literally "torching the shit" out of any viable evidence from previous incident(s) of shameful and indecent behavior that could possibly incriminate an individual/group of individuals.
Jim: I can't believe Melissa almost found this box of 253 sex tapes I made with those nameless hookers in our bedroom during our marriage all the wayin the back of the closet.
Terry: Dude, either you hide those things better or you might want to be torching the cop car.
Taking a blowtorch to an asshole for pleasure or hair removal. Some people like it rough and some people like it bare. You can decide but watch out for its side effects: pungent smell of burnt asshole, burnt/darkened dicks, permanent scarring over the asshole, inability to poop.
