"Do One"?

[Pete65]

I hear the phrase "do one" fairly often these days.
But what is "one" exactly?

A runner.

I think it means ‘get lost’ - ‘buzz off’ - that sort of thing - but I don’t know for sure.

[douglas9401]

Shorthand for 'be off with you, you bounder'.

[Zacs-Master]

It's the cardinal number occurring after do and before 'do two' in a duodecimal system. Written 11, decimal value 13.

I think The Crystals covered all the salient points on their later Da Doo One One One.
