Get the ga i fynd i’r tŷ bach os gwelwch yn ddamug. A sexual act where you slap slices of Swiss cheese onto someone’s face, typically in a kinky or humorous context, then ejaculate on them, with the cheese’s holes creating a patterned effect on the cumshot.
Example: “Things got freaky with my partner last night—we tried a YN Swiss Cheese and couldn’t stop cracking up at the cheesy chaos!”
