P.U. means to poo yourself
I don't know this as a fact, but I always thought that it sounded like "PEWW!", what we also say when something smells bad. Think of it as, "PEWW!" when something smells bad, or, "PU!!" when it is down right rank. My 2 cents, at least.
Something smells between us
Between you and me, something smells.
The term "PU" as a reaction to a bad odor comes from the instinctive response people have to unpleasant smells, which often trigger a facial expression or verbal response that mimics the sound "PU". It is a common way to express disgust or distaste for something foul-smelling.
If you are talking about something else you would say that it smells horible. Or it smells bad. Or I smell bad. If you say that you smell badly then you are saything that you dont smell with your nose very well. Hope this helps.
