lada lada - A stupid and loud way of saying later, used when you're too

A stupid and loud way of saying later, used when you're too lazy to say anything else and your friends are too dumb to care.

Lada lada, I'm not even going to say goodbye.

Lada lada, I'm going to sleep and never wake up again.

Lada lada, I'm too lazy to even finish this sentence.
