Arab Strap

Ok, there’s a band called Arab Strap, a song (and album) called The Boy With the Arab Strap…so, what the heck is an arab strap?

From the “ENCYCLOPAEDIA OF BDSM” at http://www.mikebdsm.com/encycl.htm

“Why defame the Arabs so?” is the question that springs to mind. Perhaps a sordid tale of this term’s origin is in order?
