When am I pot committed?

[Dunga Gin]

Can someone help me out here? I hear the term "pot committed" all the time but am having trouble with it. In the sense when does it happen, if the pot is X times my remaining stack size, or if I've already put X amount of my stack into the pot, or if I think my remaining stack is so small as to be almost worthless unless I win this pot, etc.

Can anyone explain the concept to me and end my confusion?

Basically, you're pot committed when you'd have correct odds to call if villain pushed.

Edit: With any cards that you could possibly have.

So the only consideration is pot odds? Well that is simple enough that even I will remember it! Thanks.
