fag n. Be exceedingly careful with this one. 1. "fag" is a very common (probably the most common) word meaning cigarette. One of the most amusing e-mails I've had concerning this page was from an American who had arrived at her company's UK offices to be told that the person she was looking for was "outside blowing a fag". 2. Almost worse, "fag" was used until recently to describe first year senior-school kids who had to perform menial tasks (cleaning boots, running errands and the like) for the seniors. A contributor tells me that he was met with aghast looks when he told a group of New Yorkers that he "was a fag at school last year". Modern thinking on slavery has seen that the practice of "fagging" has all but died out.
