Haha. One question which crosses my mind is whether the word turns out to have a somewhat artificial history. I wonder this because it seems to have no parallel in English. We have no word for walking while licking a lollypop, or walking while holding an umbrella, or walking while humming a tune. If we did, I'd feel no suspicion about a word for walking while smoking a pipe. Do other languages have words for these things? Anyway, when and where did the word originate? If it originated in 2004 on a pipe smoking forum among 23 year olds who wanted to be cool, I'll give it a hard pass. But if it has a more venerable history, that's great!
