First of the day, is actually the first drink of the day. Usually this is centered around, if in College, one waking up and instinctively grabbing beer instead of breakfast first. In other circles, this runs along the lines of taking your flask, mickey, 26er, or other bottles of liquor and swigging it - in those cases it can occur anytime during the day, preferably earlier from 8:30 AM - 1:00 PM. Continued drinking to follow.

However this term does not only apply to those who like alcohol, the term can also be used for drug use, wake and bake is synonymous with first of the day. Basically any intoxicating substance can be applied, though as a general rule alcohol is the main one considered.
From Easy Rider:

Jack Nicholson's character along with Dennis Hopper's and Peter Fonda's have just been released from the county lock up. Nicholson pulls out a mickey of Jim Beam and states,

"Here's the first of the day fellas. To ol' D.H. Lawrence."

He then swigs the Jim Beam and in a knee-jerk reaction lifts one arm and moves it like a chicken with a seizure. He makes a sound that echoes within the group,

"YA!!!!! ni-ni-ni-fu-fu-fu-gaahhhh... Indians."

The first pee in the morning. The first morning urine.
Pathologist: When was the last time you went to the toilet?
Me: At 6:00 this morning.
Pathologist: Your doctor ordered a urine test. Didn't he tell you not to empty your bladder for 2 hours prior to the test?
Me: Hmm I think he did ... but I forgot.
Pathologist: You can wait for another hour to empty your bladder or you can come back tomorrow morning?
Me: I'll come back tomorrow
Pathologist: We're open at 7:00 a.m. "First catch of the day" is always the best.... so take this vial home to use and just put it in the fridge if you can't come in straight away to drop it off.

Argueably the most anxiety producing day of school. It marks the end of your Summer vacation and the beggining of a long nine monthes back in the system. You have to readjust your sleeping habbits from sleeping in to getting up at the crack of dawn. Not that you'll get to sleep early, you'll spend most of the night anxiously pondering the awaiting day. All in all, it's not that bad. You get to catch up with friends you havn't seen over the Summer and there's hardly any work on the first day.
I'm writing this at 9:45 A.M and tommorow is the first day of school. Goodbye Summer!
