You have embraced the chaos of your powers and- in doing so- earned some semblance of control. When you roll on the Wild Magic Surge Table, you roll with Advantage.

You will roll 2d100 and choose between the surge options. It is up to the DM whether they tell you exactly what the surges would do or give a more vague description.

This feat does not grant the ability to surge, you must already be a Wild Magic Sorcerer to take this feat.
