yeah, actually, i used to always call flip flops "thongs." and then when they started getting really popular again, i absolutely refused to call them flip flops. i abhorred that name. i just wanted to scream at everyone, "THEY'RE THONGS!! THONGS, I TELL YOU!!"
but...then i started feeling ridiculous when thongs (the underwear) started getting really popular which was pretty soon after flip flops, so...i stopped. yeah, i caved pretty easily. ^_^
