Kocksure
A man possessing greater certainty than circumstances warrant. A man whose sex appeal has no limit.

Kocksureness: The state or condition of being Kocksure.
A kocksure man never says "I'm sorry", he says "you're welcome".

A Kocksure man is both a gentleman and a scholar... and only that one time a sex offender.
