A smiwey is a certain person who, whatever the situation, is not able to stop smiling in a slightly demonic smile.

A smiwle would be a slight curl of the lips with a baby voice...
An example of a smiwey is Ronald McDonald who is creepy and never stops smiwing.

or

"My mom just got killed."
"Ohh dawing I am so sorry, I hope dat she gets bettew :."

*These people in the conversation are smiling.

"I think I am a smiwey! I can't stop smiwin'!"
"You are a Smiwey."
