No one uses this phrase anymore

As Kevin points out, the greeting 'How do you do?' is a little old-fashioned nowadays. But as Duncan says, it is still sometimes used as a polite greeting in the UK. You will hear it in formal contexts - business meetings, for example - when people meet for the first time.

This is still quite common in the UK as a greeting between people that don't know each other. It's a fairly polite greeting used when meeting new people at work, or suchlike. If I introduced a work colleague to a new employee he didn't know, it would be normal for him to say it: "This is the new technician we've hired". "Oh, hi, how do you do" - probably said while holding out his hand to shake. You might also say "hi, it's nice to meet you". Less formally perhaps "how's it going", "how's things", or even "alright".

Haha no, at least not in the US.

@ Jolie Mou I'm curious to know what phrase would be a 1.
