french kissing

A look into the history of this term and style of smooch.
After I was divorced and middle-aged and back in the dating pool, I unfortunately had to kiss a few more frogs. One I recall was a tongue-darter -- very disconcerting and unromantic. And another one was worse, he had bad breath and tasted like a dried-out steak every time I kissed him. Beef is okay to eat, but NEVER to kiss.
"We have documentation to back that up," states Julio Salazar, President of the Society for the Promotion of Spanish Kissing, which is spearheading the lawsuit.
After remembering my own first kiss, I started to wonder how human beings found out about kissing. I mean how did the cave people know about French kissing even before there was a France?
