do somebody for

[ostap77]

"I heard people saying "What can I do you for, boys? Would that be correct?

[SirGod]

*Not a teacher

I have never heard that before. I would say:

What can I do for you, boys?

[ostap77]

*Not a teacher

I have never heard that before. I would say:

What can I do for you, boys?

what do others think?

[SirGod]

Hmmm, I thought about it a little bit and it might have another sense.

What can I do you for, boys?

Do meaning to have a sexual intercourse.

So, by asking that, you ask what they want you to do in order to have a sexual intercourse with them.

If you 'do' someone, you cheat them. 'What can I do you for?' is a humorous (?) rewording of 'What can I do for you' - instead of saying 'How may I be of assistance to you?', the person is asking 'How can I cheat you?' Ho ho.

It's a frivolous, slightly humorous (the first time you hear it, anyway) inversion of 'What can I do for you?' ('How can I help you?')

To do somebody also means to cheat them, so the implication is 'How can I fleece you boys?'

It's just a flippant, casual mangling of the language by a friendly waiter, for example, trying to mildly entertain his customers, in the same way he might ask 'How are you diddling today, boys?'

You can read sexual or whatever connotations into it, but in ordinary circumstances it simply means "How can I help you?". Shop clerks or servers say it sometimes. Not meant to be creepy.
