Ghost-Half is considering doing hula dance. Either that, or "he thinks he's hula dancing but he's not"; guess it could go either way judging by the context.
This is why I can never consider learning Japanese. This fucking language can have you go "I love you with my entire soul", or "my butthole is flowing with liquid shit", all depending from context. I bet it inspired Warhammer 40000's Eldar language where words mean literally one thing and its opposite depending from, again, the bloody context. I hate context. All my homies hate context. Let's find context, beat him him, and steal his shoes!
