Well, flounder no longer. That acronym, along with about 1,700 new entries, have just been defined in Merriam-Webster’s latest update to their unabridged online dictionary. The American reference provided a selection of the new words on its blog. Many embody our modern obsession with digital life (_clickbait, NSFW, emoji_). Others will teach future generations about the curious fashion choices of people living in the early 21st century (_jeggings_). And still others provide a linguistic term for our tendency to mishear Elton John lyrics as “Hold me closer, Tony Danza” instead of “Hold me closer, tiny dancer” (_eggcorn_). Here are the definitions that the lexicographers at M-W came up with for this latest reflection of who English speakers are and what we care about: **WTF (abbrev.)** _Definition_: what the f—, used especially to express or describe outraged surprise, recklessness, confusion or bemusement. **NSFW (abbrev.)** _Definition_: not safe for work;
