Popping is an actual dance style. This is not the umbrella term for the whole dance. The umbrella term is not funk styles either, but Boogaloo Sam has said that the umbrella term is Boog style. There are three different ways to dance if you are following Boogaloo Sam's or EB's pattern: Poppin, Boog, and Boog style. Poppin is a continuous flexing and releasing of the muscles in your neck, body(chest, back), arms(biceps, triceps, forearms), and legs(buttocks, thighs, calf muscles). If you are a Popper, according to Sam's definition, dancing at a Poppin competition you cannot wave. You strictly Pop. If you wave, from the definition given, then you are considered Boog stylin. If you are Poppin and then you Scarecrow, you are no longer Poppin, but Boog stylin.
Popping is still having that "feel" like in Boog, hitting all muscles patiently, walking your arms, sitting hard inside the music, being simple, funky, smooth, doing walkouts, twist-o-flexes, master-flexes, egyptian twists, romeo twists, neck-o-flexes, and fresno.
Boog as defined from the source, is a type of "feel" or "flavor" when one dances. Also, Boog is an actual dance style(not a series of moves, but a continuous dance style). You don't have to roll everything at once, but more so being very patient with the music, and having that "feel". Boog is different from Boog style. Boog is a "feel" and an actual style. Boog style is when you still have the Boog "feel" but you are adding other styles in with it.
Boog: Patient, funky, smooth, simple movements yet dancing very complimentary inside the music.
Boog style: The same "feel" as mentioned above doing scarecrow, robot, and rock waves.
