5 o'clock

happy hour, the international drinking time, sort of like 4:20 is for smoking the reefer.

"Pour me something tall and strong, make it a hurricane before I go insane.
It's only half past 12 but I don't care...it's 5 o'clock somewhere." -Alan Jackson/Jimmy Buffett

5-O

5-0 became a slang term for law enforcement (aka police) after the hit show "Hawaii Five-O". The show was centered around a fictional division inside the State-Police of Hawaii and carried the same name as the television show ("Hawaii Five-0". The division's name gets its origin from honoring the fact that Hawaii was the 50th state to become apart of the United States of America.
On a side note, the division was actually called "Hawaii Five-0" (as in Zero, no the letter "o") but IMDB has the show listed with the letter "o" in the tittle.

The Five-0 (5-O)had set-up a speed trap and gave me a hefty ticket!

When a male doesn't wish to look baby smooth on his undercarriage so he leaves a very short defining stubble. Such as 5 o'clock shadow, but for his Zamboni.

You: Yeah i do!
Friend: Better shave up in case she wishes to examine your crime scene...don't go overboard though.
You:No worries i already have the 5 o'cock shadow going.
Friend: Bro?
You: Bro!

5-O

5-O goes back even further than California late 80's. It's origins are a reference to an old 70's TV show called Hawaii 5-0 starring Jack Lord. The police were 5-O and eventually the show lingo caught on as hip among petty criminals in southern California.

"STOP, Hawaii 5-O!!!!"

....blah, blah, blah- small struggles, throw a few punches - handcuffs criminal and stuffs them in the back of a patrol car ....

"Book 'em Danno", said Steve Garrett.

"naw....just a bunch of A-3-5-O's..."

5 o cock shadow

It is when you shave your balls and surrounding areas and the hair starts to grow back. Like a 5 o clock shadow on your face but the one on your most manly of areas.

My friend took a picture of my cock and balls it was so clear you could see my 5 o cock shadow.

5 o'clock cheesy shadow

When one develops an orange stain around the lower face after a day of sitting on the couch and eating Cheetos.

The mark of a true couch potato.

Girl 1: I come home from work every day and my orange-faced boyfriend is just sitting there with the remote.

Girl 2: Uh oh, its a 5 o'clock cheesy shadow.
