Doin' the Bump 

In what might be called a much earlier form of "twerking" (see Urban Dictionary for definition), the more versatile "bump", an extremely popular dance craze of the early 1970's, involved repeated and often continuous partner-to-partner hip contact of several specific varieties: rear to rear, side to side, front to rear (as in the aforementioned twerking), and last but not least. the mutual frontal option consisting of the thrusting of the partners' groin areas against each other in what can perhaps only be described as a sort of "dancing dry hump".

Man, can you believe it; I was doin' the Bump so good with this super hot chick at the party last night that I had to say to her "If we keep this up I won't be able to do anything else later!"
