The rules strictly forbid anyone to post any link to a video or audio file without prior approval from a moderator in any case. I'm afraid that you'll have to describe the situation for us. What's happening in the video? What's the name of the song? What are the singers/dancers doing and how are they dressed?
No, they're not dancers or singers. It's a blooper from a scene of the serie Gossip Girl. Two of the characters are in a ball or something like that and the guy threw her back and said "care for a dip?" and then they started laughing.
