Toodle-oo
Toodle-oo..... I really like this word...Early 1900's.
Mostly British.. Ah the British....
I think it is important to "learn" how to use this word.
So much nicer then "Get lost!" or slamming a door.
Etymology:
"perhaps imitative of an automobile horn"
We use it too
Toedeloe but the youth might no longer use it. It sounds happy and in a way like 'I'm off, don't stop me till next time'
