• Get all the video IDs, then create a URL like so:

http://youtube.com/watch_videos?video_ids=AAAAAAAAAAA,BBBBBBBBBBB,CCCCCCCCCCC,DDDDDDDDDDD

• It will redirect you to a link like this:

http://youtube.com/watch?v=AAAAAAAAAAA&list=EEEEEEEEEEEEEEEEEEEEEEEE

• If you want to share, you can shorten it to this:

http://youtube.com/playlist?list=EEEEEEEEEEEEEEEEEEEEEEEE

• (Addendum) Playlist creation with playlist name:

http://youtube.com/watch_videos?video_ids=AAAAAAAAAAA,BBBBBBBBBBB,CCCCCCCCCCC,DDDDDDDDDDD&name=PlaylistName
