Whereas " belisle " is a French word as well as English indicating a trap for foxes, http://www.snareshop.com/products.asp?dept=468 it's surprising to find it elsewhere with a very shocking meaning as shown there : http://www.urbandictionary.com/define.php?term=Belisle
the etymology of belisle is "belle île" which means "beautiful island"
but I don't know why "belisle" means "fox trap" nor the link between it and a sexual violence. Could you explain where this distortion comes from ? Many thanks
