It means that you have the ability to completely control the newly found blocks.

Basically you can:

Orphant all Blocks from other miners
Completely decide which transaction get confirmed and which not
Invalid already confirmed transactions that have happened at the time you already had over 50% of the Hashing power (double spend) by orphaning existing blocks

What you can't:

Steal someone coins
Make any behaviour that is against the protocol, like for example create new coins out of thin air
