Pooping

Popping is a dance style and one of the original funk styles dances that came out of Fresno, CA in the 1970s.^[1] It is based on the technique of quickly contracting and relaxing muscles to cause a jerk in the dancer's body, referred to as a pop or a hit. This is done continuously to the rhythm of a song in combination with various movements and poses.
^[1] Popping is also used as an umbrella term to refer to a group of closely related illusionary dance styles and techniques that are often integrated with popping to create a more varied performance . 
^[2] A popping dancer is commonly referred to as a popper.
Like other styles of street dance, popping is often performed in a battle trying to outperform another dancer or group of dancers in front of a crowd. This gives room for improvisation and moves that are seldom seen in shows and performances [also referred to as freestyling]. It also allows for interaction with the other contestants and spectators.
