Semo is a word describing someone who likes
chapped stick, listens only to the best bands like
Relient K, Hawk Nelson, Underoath, Bleach, Mae, Anberlin, and most other Tooth and Nail artists. You surf, or some other kind of
water sport, and have a love for wrist bands, and dressing up like your own favorite band.
Came from a band named Achoowawa. 'Emo' kids say that you can't surf and be emo, and it just happens the lead drums, lead singers, and lead guitarists of Achoowawa do surf, so the 's' was added in front of emo.
If you see someone wearing a
plaid shirt, and / or has a
fanny pack, and / or has shoes on that don't match but still look
really cool, and / or and has a surf board... you'd say "That's so semo"
