What's does this mean????

Prince says it all the times in some of his earlier songs. I've also heard Parliment/ Slave and Ohio Players say it in there songs?

Put your foot on the rock
Let the girls see ya
Put your foot down on the 1
Shake your body, have some fun

It certainly does not have to mean anything.
I think he means beat.

Wheneve rhe used to chant The Roof, The Roof, The roof is on fire! I certainly did not look for fire extinguishers...

Yeah,,

But for example,,, The Roof, The Roof,, is a chant that came from another song.
I was wondering if that saying came from another song also. Like a James brown track or something.

next thing you know, you're going to ask us to show you how to clock.

I already know how to do that.

Check Bill Withers' 1972 cut "Kissing My Love" from the LP Still Bill if you wanna know the origins of "...put your foot on the rock..."
