flip-flops vs. slippers vs. clackers

So, lately I've received a lot of flack about the word "flip-flops." Apparently everyone who thinks they have any naming rights to the aforementioned footwear calls them "slippers." Now, now, don't get all up in a huff my fellow 'mericans. I decided to do some thorough internet research to settle this debate once and for all.

A google image search of the word "slippers" yielded 83% actual slippers, and 17% australian/hawaiian "slippers" aka "flip-flops." It also yielded this...

Meanwhile, a google image search for "flip-flops" yeilded 95% actual flip-flops and one unpostable picture of a foot rash.

However the reason I am posting this is that today, while walking, I realized maybe those Ausies were right. My flip-flops didn't seem to be audibly "flip-flopping." Indeed there was some "flip-flop" action but, you know, I always thought it was named after the sound. And, the noise they were making was more of a "clack" or a "thwack". The sound had a negative air suck quality to it that "flip-flop" doesn't quite cover. Clearly "slippers" would be a poor substitute. Being the diplomat that I am, I propose another resolution to this debate. Perhaps we can call them "clackers" or "thwackers" or some alternate name that onomatopoeia-izes (sorry OED) this versatile footwear. Suggestions?
