Remember all those times when you were younger and you tried to impress your friends by saying what you thought was the longest word in existence? (No? Just us?) Well, as it turns out, supercalifragilisticexpialidocious isn't as impressive as we thought. Sorry, Mary Poppins.
The word we're talking about is actually way too long to include in this post, but you can find it here. It has 189,819 letters and would take you 3.5 hours to say, according to Gizmodo. Talk about a way to pass time.
On that note, if you ever need to say the non-abbreviated name for the chemical Titin for whatever reason, you'll be well-versed. You're welcome.
