Does the term rock and roll have its roots in engine anatomy?

I was doing some studying on engine anatomy and noticed that there is a "roller" type of valve rocker. It is known for alleviating unwanted friction in the valvetrain, thus, increasing performance, so It would seem fitting of the early rock and roll/ hotrod sub culture. Any thoughts?|||No. It was an old jazz/blues/R%26amp;B euphemism for sex. In 1937, Chick Webb and Ella Fitzgerald recorded "Rock It for Me", which included the lyric, "So won't you satisfy my soul with the rock and roll". The verb "roll" was a medieval metaphor which meant "having sex". Writers for hundreds of years have used the phrases "They had a roll in the hay" or "I rolled her in the clover". The phrase "rocking and rolling", was secular black slang for dancing or sex by the early twentieth century, appearing on record for the first time in 1922 on Trixie Smith's "My Man Rocks Me With One Steady Roll", and as a double entendre, ostensibly referring to dancing, but with the subtextual meaning of sex, as in Roy Brown's "Good Rocking Tonight" (1948). Alan Freed was the first to use the term to refer to Popular Music of the 1950's, and he did so in reference to it's jazz/blues/R%26amp;B roots and danceability.|||No, I was 15 years old when Rock Around the Clock ( Bill Haley %26amp; His Comets ) came out in 1954. Alan Freed ( New York ) coined the phrase; Also there was Fats Domino,Little Richard, Elvis, The Commodores, etc., etc.. That was the year I got my first Harley-Davidson, 1942 WLA, and my first car ( 1938 Chevy Coupe ) ! I was like Braveheart; FREEDOM !|||umm
