Top definition
A person who is exceptional at taking time off work, without anyone noticing.

This person has minimal work ethics, and usually comes in late, has long lunches and leaves early - making up silly excuses.
Andy: I am rolling out at 4.15 today. Fuck that 5 O clock shit.
Roscoe: Damn, how come?
Andy: Haircut. Ill do that shit on work time.
Roscoe: Damn Andy, you got in at 10, had a 3 hour lunch and leaving at 4.15! Your the Half Day King!
Andy: Word, yo.
