Bobs Your Uncle?

It’s a British slang……. It is added to the end of sentences a bit like “and that’s it!”

For example if you are telling someone how to make banoffee pie you just served them, you would tell them to boil the condensed milk for three hours, spread it onto a basic cheesecake base, slice bananas on top, add some whipped double cream, another layer of banana and Bob’s your uncle!

It’s known mainly in Britain and Commonwealth countries, and is really a kind of interjection. It’s used to show how simple it is to do something: “You put the plug in here, press that switch, and Bob’s your uncle!”.

It means, like when you say I can do that faster than you can say”Bob’s your uncle”

That Bob is indeed your uncle.

“And there you go” “there you have it” or “Bob really is your uncle”

and ruby`s your aunt
