Grundulation

Showing someone a funny video, but then you realize they don't find it funny, but you can't pull out, and they don't wanna be rude either, and there's 30 seconds left that you know will not be funny either.

Showing him that video was an absolute grundulation! He didn't move for a solid 5 minutes.
