Rock & Roll

(from Wikipedia)

"...the phrase "rocking and rolling", as secular black slang for dancing or sex, appeared on record for the first time in 1922 on Trixie Smith's "My Man Rocks Me With One Steady Roll". Even earlier, in 1916, the term "rocking and rolling" was used with a religious connotation, on the phonograph record "The Camp Meeting Jubilee" by an unnamed male "quartette".^[5] The word "rock" had a long history in the English language as a metaphor for "to shake up, to disturb or to incite". 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." "Rocking" was a term used by black gospel singers in the American South to mean something akin to spiritual rapture. By the 1940s, however, the term was used as a double entendre, ostensibly referring to dancing, but with the subtextual meaning of sex, as in Roy Brown's "Good Rocking Tonight." 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"^[6]..."
