The phrase "you've got to ___" can have several different meanings, depending on the situation and how you say it. It could be:

• An explanation:

  You've got to turn your card the other way or it won't work.

• A strongly-worded suggestion or command:

  You've got to get out and start looking for a job!

But when you're talking to family or friends, you can also use "You've got to ___" to beg for something that you want from them. It may seem kind of rude or demanding, but it's not. It just sounds like you really want the listener's help.

Here are some other examples:

I saw a ghost – I promise! You've got to believe me!

You got tickets? That's so awesome! You've got to let me come with you!

By the way, sometimes people say "you" instead of "you've" and pronounce "got to" in a way that sounds like "godda".
