A person who portrays themself to be something that they are not. Uses their cuteness to hide the evil they carry inside. Always out for themselves and will always get what they want at the expense of others.
During a a game of Kings:

Me: ...Nine?
Kieran: Nope! Seven, drink up cocksack!
Me: You untrustable bastard...I hope you die from a botched hysterectomy
