A physical representation of the friend zone. If the person, male or female, does this to you, you no longer have any chance, a final nail in the coffin.

Almost as comforting as a mother's touch when you have the flu but as awkward as a penguin trying to balance itself on your shoulder just moments before losing its balance while waddling on land. A Quote from a leadership book found inside the commander’s office, “Daily physical contacts with your subordinate builds a culture of trust within your formation. This includes high five, awkward side hugs, or a comforting shoulder pat.”

When you have to pretend to feel sorry for someone, but you really don't, so you just give them the most awkward, non-comforting shoulder pat in the world.
