Stands for "pleasant physical contact", such as when one or more blinky-eyed cuties obligingly slap yer hand wif their own soft warm palms as you walk by them, or when an attention-seeking toddler smilingly raises his/her arms to you in a "please pick me up for snuggles" gesture, and so you cradle him on your lap and savoringly share a few moments of contented cooing closeness before said pint-size jumps back down and happily patters off to play again.
Playing "pinkie-tips" (i.e., lightly pressing da pad of your little finger against that of your friend on your way past him) can be a good alternative to a high-five on a hot day --- you and your friend still get to enjoy a little P.P.C. without getting too "close 'n' personal" when your hands are all damp 'n' disgusting.
