You just got home and sat on the couch relaxing, when your roommate Tim came into the room, he, as always, started telling you something... About a new piercing, about how he played hockey today, but while he was yapping something there, you did not ignore the huge black "X" symbol on his hand and directly asked what it was.
Tim fell silent, looked at you with a raised eyebrow, and then when he realized what was being discussed, he smiled and pointed his finger at his hand, explaining.
"That's uh... That's a symbol of my pledge. See, I'm denying myself certain pleasures, eh?" He started counting on his fingers. "Eating meat. Drinking alcohol. Sex."
You looked at him questioningly, as if he had come up with some nonsense again that only he understood.
"Yeah, all forms of sex." Raising his hand, he waved his fist in the air, imitating exactly this.
