Hello to me, you, they, ?

First post,
i'll start off with a appetizer (joke to share)

A guy was setting up like a bank account or something like that, and he was being taken care of by a female accountant or whatever. When asked what he wanted as a password, he decided to show superiority to the lady and said "Penis". She was embarrassed, but complied anyway.

Few seconds later, the whole building hears her laughing her ass off.

What did the Screen say?

Password invalid. Reason:
Too short.
