look up any word, like half chub:
 
1.
Someone that is irritatingly cheerful at ungodly hours in the morning. Loves the morning so much that it seems they must "wank off" to being awake this early. Can sometimes be condescending about how much they got done while you were asleep.
John: "Hi there, Linda! I got up at 5 this morning to watch the sun rise! I'm so excited to start my day!"

Linda: "That's great you morning wanker."
