To dance with awesome style, or like a badass. The word was made popular by both the funk band The Ohio Players and the grunge band Soundgarden in the song "Fopp".
Fopped so hard I made the people roar,
They stood back and gave me all the floor.
Yeah I was foppin' and rockin'
Had the whole house boppin'
They stood back and gave me all the floor.
Yeah I was foppin' and rockin'
Had the whole house boppin'
