The act of shaking ones butt to the beat of music (or without music) as a mating call to attract men.
"Twerking" is usually seen as a dance move to dirty songs. Women normally get against a wall, stick it out, and show the whole word what their momma gave em. Men find this maneuver attractive of course (since a girls butt is practically begging them to hop on) depending on the twerker and how good she can shake it. Some women may do this to attract attention to themselves though they may find it may not exactly be the attention they were looking for..
Twerk or the plural term "Twerking", means to shake the ass around in a fast, sexual act of arousal. Usually performed by hot females, usually having a large butt. Can be performed by men, but it's usually not meant to be sexual in any way.
