Flash Muscle

The large, basically useless muscles of bodybuilders, Californians and Jersey Shore Characters.

Mike "The Situation" has a lot of flash muscle. Urijah Faber could beat him with one hand.

Flashing the Dan

Get the Flashing the Dan mug.

When a woman (or possibly a man) wears a button-down shirt that is a little too tight, resulting in the fabric straining at the buttons, and forming a gap. This allows friends, family, and/or the general public to have a glimpse of your side-boob.

"Oh man! That girl should really put a sweater on."

"Why?"

"Because she's totally gap-flashin' the entire coffee shop!"

Flash train-logic

The concieved notion that you can accomplish anything, simply because it is required of you in that moment. Even if you have no background of doing this or there's been no setup for you being able to do this in the past.
Basically a lousy way to explain away a Deus Ex Machina.

As seen on the Flash:
The Flash somehow manages to get a train to vibrate at the same speed he is, so that the train goes through some rubble in the road.
Later:
Kid Flash: "How did you do that?"
Flash: "Because I had to."
Me, watching the show: That's some Flash train-logic right there!"
