An imperious reply that an authority figure --- most often a parent --- impatiently tells someone under his/her care when he does not wish to admit that there is literally no good/valid reason why said dependent should have to comply with the directive, but the authority figure doesn't want to admit it.
Kids are smarter than you think --- if you tell them, "Because I said so!" even just once, they will never trust your judgement again.

I've had enough of listening to your drivel. Begone!

As spoken memorably by the inimitable Gene Wilder as Willy Wonka himself in "Willie Wonka and the Chocolate Factory":

Grandpa Joe: You're a crook. You're a cheat and a swindler. How could you do a thing like this, raise up a little boy's hopes and then dash all his dreams to pieces? You're an inhuman monster.
Willy Wonka: I said good day!

The answer that most parents, (mostly moms) will give their child when they dont want them to do something or go somewhere. It is said because they know the child knows they have no answer, so they will simply say, Because i said so!
Billy: "Mom c'mon, please let me stay at Ben's tonight!"
Mother:"No Billy."
Billy: "Dammit why not!"
Mother: "Because I said so!"
Billy: "That's not a answer mom!"
Mother: "I'll pick you up in a hour, bye" **click**
Billy: "FUCK!"

Signature line by the character Fez of the TV show That '70s Show. No matter the conversation, it always ends when Fez says, "I said good day."
Fez: "Good day."
Eric: "But Fez..."
Fez: (Interrupting) "I said good day!"
