10:30 

A 10:30 is a special sandwich you can get at McDonalds, but only if you order at exactly 10:30 a.m. The 10:30 is a cross between a Big Mac and an Egg McMuffin, containing beef, egg, special sauce, and McMuffin. At 10:30 a.m. McDonalds changes over from their breakfast menu to their standard menu. At this point in time they will have both fresh Big Macs and fresh Egg McMuffins available. If you order at precisely this time, and ask the cashier for a "10:30," you will be able to experience the apex of fast food. If you don't ask for the 10:30 by name you probably won't get one.

"Excuse me miss, can I get a half Big Mac half Egg McMuffin?"

"Um, I don't know what you're talking about and we stopped serving breakfast."

"Hey baby, let me get a 10:30" *wink*

"Alright." *smiles and nods*

Similar to 4:20, it's for parents of small children who wait until after the kids are in bed before they smoke pot.

Old friend: Happy 4:20!
Mikeyramone74: Not anymore. I have to wait until the kids are asleep. Hit me up at 10:30.

10/30 movie watching method

Who needs to watch a whole movie nowadays? The first ten minutes give you enough of the story, while the last thirty minutes contain most of the movie's action.
It's the 10/30 method.

I must give credit to Javier for this one.

I watched District 9 using the 10/30 movie watching method. Great movie.
