When I was young, my father didn't want to swear in front of the kids. He used to say arse, instead of ass. After a few years, the kids knew what he meant when he said arse, so he had the ingenuity of changing arse to harse. That's the best explanation I can come up with, but most likely it is just because he is a harse and likes to make up words.
Glenn, I know you are a bastard, but you don't have to be a harse too.
Most workplaces require employees to wear an ID badge with their name and picture on it. Many times these badges are clipped to one's waistband or pocket. When visiting a rest room stall and lowering one's pants, the ID badge can hang below the stall divider, where the next person can see it; thereby informing that person precisely which of their coworkers is dropping a deuce next to them. I.Deuce. badges really up the awkward factor in a rest room setting, especially when the badgeholder is a high-up executive, or worse, a flatulent overeater.
Was just taking a dump on the third floor and saw Fat Al's I.Deuce. badge in the stall next to me. I cut my visit short and ran out of there before the fireworks started.
