The vaguely-triangular strip of road separating a highway exit from the actual off-ramp. So named because drivers will use the space to stop and make decisions, merge through to the off-ramp after making split-second decisions, and/or crash into water-filled barrels or exit signs contained therein after failing to properly make a decision.
(To a passenger) Did you see that guy cut through the decision lane?
(To another driver) Nice use of the decision lane, idiot!
(Relating a story) Ted really needed to stop, so he parked in the decision lane.
(Relating directions) You can merge off the ramp that's next to the decision lane without any barrels.

Similar to Cocaine Decision an irrationally optimistic impulsive decision to start a vintage or retro small business, with no idea of who will actually pay good money for the flowery-heart-craft-thing, wavy hair or indeed cupcake, that is proposed.
"It's on handmade paper with natural dyes and each one takes 2 hours of my time so I think fifteen pounds for a birthday card is fair, right?"

"I love the whole retro look and at least 2 of my friends bought some off me so everyone will..."

"Have you thought that through? sounds like a cupcake decision to me..."

Decision stream - a statistic-based supervised learning technique that generates a deep directed acyclic graph of decision rules to solve classification and regression tasks
By increasing the number of samples in each node and reducing the tree width, the Decision stream preserves statistically representative data and allows extremely deep graph architecture that can consist of hundreds of levels.

Anything that one does to veer away from something normal. It applies to sibling rivalry or going against peer pressure. It also can mean something that you do that is boldly different.

Military term;
the act of arriving at a decision and acting upon it without the direction of, or orders from a higher authority. i.e. an independant course of action without the sanction of a superior.

"Corporal, who told you to toss that live round over the side? Don't you realize that this is a waste of government property and you could be charged under a violation of section 118 of the articles of war?"

"Yes sir, I felt I had three options: knowing that a round which falls on the deck is considered to be a hot round and therefore unsafe; I could have left it to roll around the deck and detonate in its own time, or I could retreive it and place it in the hopper to be fired off, thus risking the lives of the three guncrew if it detonated while still in the hopper; or I could elect to throw it overboard."

"I determined that the risk wasn't warranted and so I tossed it."
