Contexts include NSFW text ("dirty words"); punch lines for "Think about this *then* read the answer" jokes, riddle answers, and the like; various types of guessing games (or possibly "Try to guess my answers to this meme-thingy"); anything where you want people to have to make a conscious and deliberate decision to read a particular short word or phrase. I would think fan / fanfic / spoiler contexts would be more suited to cuts anyway, because fen post long things. ;)
