I hope your reindeer 'pip' wasn't the same as the 'pip' my mother told us we'd get if we sat on the cold ground or a brick wall...

She never could explain to any satisfactory degree just exactly WHAT the 'pip' was, but that's because it would have involved the use of the word 'bottom' and my mother was way beyond reluctant to mention any body part that had to be covered with underwear.

Consequently, after years of sitting on the cold ground or walls, I could have the 'pip' and not know it... or it may just be piles.
