A group sexual position named after some airline (ask around an airport and you might figure out who and why) in which the recipient of The Delta assumes a "diaper changing position" and is penetrated anally and punched in the nuts (or vagina) by one partner, as the other partner strangles the recipient with a telephone wire and shits in their mouth.
If you travel enough or work for an airline sooner or later you will know exactly what "The Delta" feels like.

Get the The Delta mug.
Highly effective soldiers skilled with all weapons systems, tactics, and hand to hand. Have mastery of at least two languages. Extremely polite and educated, they won't pick fights. If you absolutely need someone picked up or just dead, that's who you would want. Quiet, fast, and dead-on accurate. Normal and unassuming. When it all goes wrong, you want them in front - or if you're really fucking good, you'll be at their side.
Oh fuck man, I think that's delta out there. I'm gonna eat a bullet before they get here.

Fourth letter in Greek alphabet, the word Delta means a change in quantity (more rarely quality).
Take the value for the first day of each week and subtract it from the value at the next to obtain the weekly deltas.

Rates have gone up, but I converted to fixed, so my Delta hasn't been too bad.

noun: a very selfish and disgustingly ugly girl who resembles the upper part of the human ass crack and who shows no concern for anyone around her because she is fat but thinks she is beautiful. many of the common signs that a girl may be THE DELTA is that she is a very fast driver and complains about everything.
THE DELTA was talking shit about an ugly girl and said to the person sitting next to her "thank god i'm not as ugly as she is!" then the person responds "you're looking in the mirror."
