: Which way is upside?
: In the US, when somebody slaps you "upside your head", is that a downward blow from above, or an upward blow from below? The word isn't used in the UK.
I don't think it really matters. IMO, upside in this phrase is not directional but positional - it basically means the same as beside, alongside, against the side of. I would expect a straight across slap against the side of the head.
