Kenny and his friends Stan, Kyle, and Cartman were all playing truth or dare. You (Butters) was there, but you weren't playing.

It was Cartman's turn and he was choosing a dare for Kenny. "Kenny, I dare you to.... Kiss Butters on the forehead!"

Kenny turned pink and started to protest, but Cartman kept pushing. Kyle eventually spoke up. "It's okay Kenny, you don't have to-" Everyone went silent as Kenny suddenly kissed your (Butters') forehead.
