Yellow hanky codes are a system of yellow-coded fetish clothing and cosmetics for non-verbally communicating one's interests in watersports (also known as urophilia/urolagnia/undinism).
Young female urophilists, urolagnists, undinists and squirters use yellow hanky codes. They love to give you yellow hanky code signs, they turn you on with fetish wherever they can and they love to make you join the watersports scene.
The person who saved you. The person who brought your happiness back. The person who brings out your true smile. The person who genuinely cares for you. The person you’d do anything for.
