Is this sign appropriate for adults to use?
While tapping a "P" on the nose is widely understood, adults typically use the sign for "bathroom" or "restroom" in polite company. The sign for "peepee" is most commonly used when speaking with children, pets, or in very casual settings.
Can I use my left hand to sign this?
Yes! You should always use your dominant hand for one-handed signs. If you are left-handed, simply form the "P" handshape with your left hand and tap your nose.
What is the difference between the 'P' and 'K' handshapes?
Both use the exact same finger positioning, but their orientation differs. For a "K", your fingers point upward. For a "P", your wrist drops so your fingers point forward and down. In this specific sign, the hand is angled so the middle finger can easily tap the nose.
