I have seen it as usage of 很棒, but I don't get how that means thumbs up as it were? Was I misunderstanding the comment on the video??
I know that on mdbg.net there is a different meaningg = = ~~~~ : )
It says: stick / club / cudgel / smart / capable / strong / wonderful / classifier for legs of a relay race
Whenever I search it on Google images, it only shows thumbs up..O_O
I seen this on a video about 楚辞, I think it is worth a share :)
