Ask

What you do when you want a prom date. In finance, the ask or the bid-ask is what the seller wants to sell for. The price includes the commission or other fees the dealer will get.

So, basically, a seller asks and a buyer bids and once these bids and asks get together and pair up, it becomes the price. And that's how baby prices are made (hope we didn't get too graphic, but we think you're old enough).
