This is actually a double-hashtag eg pinned instructions for Feb 16th 2016: “It’s game time! Last week we discussed love, today we’re all about humour. Share what books, characters & lines amuse you –> #laughsinlit” In this case, you would use both the #Quill and the #laughsinlit hashtags in one tweet.
