the patch of cum that stays on the skin for a long period of time either after a man ejaculates on himself or someoine else, which causes it to dry. once the skin is stretched out, you can feel the skeet pulling the skin.
After having sex with my girlfriend, I skeeted on her but waited too long to help her wipe up. It dried up so when she went to get up, it created a dry stretch. She wasn't too thrilled.
