When Someone asks what it do, and you do something, you respond with "thats what it do" Or when you make a definate statement.
ex 1) guy 1: "what it do with that new whip?"
guy 2: (does a donut or figure 8) "thats what it do"

ex 2) Killa Keise - "I can go home and pull 50 racks out that Jordan box, thats what it do nigga, they call us guap gang from now on nigga:"
