a smylie is someone who can never be in the wrong, or they will
combust. Usual side effects of being a smylie include bleached
hair, being really really tall (much taller than any of their
friends) and having the sensitivity of a princess.
"oi princess, you've got a spot"
"shut up, get lost, surprised you can see from DOWN THERE"
"dude - stop being such a darn smylie, you're but an inch
greater in height!?"
"no it's not..."
