Lesson in Word Origins:

Scott: At Oxford University, young men were assigned as aides to the seniors. Part of their duties was to gather bundles of sticks also known as “faggots” and you know what they would do?
Me: Um, stick ’em up their butts?
Scott: Well, no. But they would perform sexual favors for the older boys and it evolved into the derogatory meaning of “faggot” as we know it today.

So, now you know.
