where did the term flip flop come from
Flip-flops The term flip-flop has been used in American and British English since the 1970s to describe the thong or no-heel-strap sandal. It is an onomatopoeia of the sound made by the sandals when walking in them.[1] They are called thongs in Australia,[2] jandals (originally a trademarked name derived from "Japanese sandals") in New Zealand,[3] slops in South Africa[4] and tsinelas in the Philippines (or, in some Visayan localities, "smagul", from the word smuggled).
