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.
"My boyfriends dick is darker than usual, I think he was asshole torching."
A well-guarded secret greeting amongst men that may only occur in the absence of women. It is performed by pressing the tips of two penises together, head on, forming a straight veiny line. Verbal consent is strongly recommended and eye contact is not advised. Can be used to determine if a male is circumsided without creating an awkward or uncomfortable situation.
"Hello there fine Sir, interested in Touching Tips?"
"Of course, how could one turn down such a reasonable request."
*touches tips together*
"Perfect, but I couldn't help but notice that you're circumcised."
"What a keen and correct observation that you have made."
