When you are at a restaurant and have a drink that the waiter asks to refill. You say no. Thirty seconds later, your drink is full and you have no idea what happened.
Waiter: Would you like more coke?

You No thank you I'm fine.

Waiter: okay...

***30 seconds pass***
You go to take a sip and your cup is full.

You:....What the...wow...Ninja refill

Someone who jumps to the front of the line at a fast food restaurant counter to get their drink refilled before the person they have cut has a chance to place an order.
"Dude, I was about to order a number 7 at Taco Bell, when this refill ninja totally cut in front of me. It happened so fast I didn't have time to react."
