Taking normal, everyday things and making them extreme. Slang term introduced into the
Greenville, OH region. Thought to have been introduced by people who would do unnecessarily extreme things like rip
sleeves off of shirts, wear sleeveless shirts in cold weather, and drink highly
caffeinated energy drinks.
The douchebag had to "Sheltonize" a perfectly good t-shirt by cutting the
sleeves off, so he could be a sweet broseph and wear it to the gym.
The guys at the gym "sheltonized" their
flow session by drinking
AMP before hand.
