You may put a creature card from your hand onto the battlefield. If you do, sacrifice it unless you pay its mana cost reduced by 2 generic mana .
No tactic transforms a battle like a well-timed carnivore.
Rulings (4)
If you choose not to pay, the creature is sacrificed immediately. No player will get priority in between the creature entering the battlefield and being sacrificed. Sacrificing the creature this way will trigger any abilities that trigger when it leaves the battlefield, and those abilities will be put onto the stack at the same time as those that triggered when it entered the battlefield.

If the creature has X generic mana in its mana cost, X is considered to be 0.

The creature enters the battlefield, so it will trigger enters-the-battlefield abilities even if you choose not to pay.
