I say swell a lot. My friends think it's weird, but I'm trying to bring it back.
I find that people usually laugh or smile when I use swell. I mean it's a fun word. How can you not smile when you say swell? I once got my entire class to start using swell, even my professor frequently incorporated the word into his emails.
It's different and that's what I like about it. I'm not a big trend follower. I don't really enjoy Today's Top Hits, watch reality television, or read the top grossing book. Just because something is on a Top 25 List doesn't mean it's a Top 25 for everyone.
Sure, people think it's a bit strange to be using a word that died with the end of the 1960s, but I think normal is overrated.
