Q.E.D.

Formally used at the end of mathematical proofs to indicate their completion, informally to indicate an argument has been won. Literally "Which was to be demonstrated" (not just "which was demonstrated").

... Yeah well, I checked; they don't make dildos that big. Q.E.D.

Q.E.D.

A word used by intellectuals that, apparently, they are quite sensitive about if you translate incorrectly. Causes redness and itching on mathemeticians when misused.

Bert- "Q.E.D. means "quit earning dough." It's what you do when you decide to become a professor, right?

Professor Hubert, PHD- "I hate you, I hate you, I hate you!"

q.e.d.

abbreviation for Latin- "Quam Effusio Deleo," or 'How one annhialates enthusiasm, excitement, interest.' when someone uses this term in any form, understand they are trying to put you to sleep and violate you while you drowse, and probably take your wallet, regardless of how smart they sound, that drone you're hearing is only a substitute for the hypnotist's watch.

Professor Blumpkin finished his thesis with "and so you can clearly understand what I have demonstrated. It is simple, Q.E.D. The next thing I knew someone from the back row of the lecture hall was yelling, "Yo, Jimmy, look out" I roused myself to see Blumpkin removing his hand from my crotchal area. "What?" He protested, "I had just dropped my laser pointer, is all."

Q.E.D.B.

From the Latin "Quod Erat Demonstrandum" which translated to English means "Which was to be demonstrated" ergo "Case in point".

The "B" at the end stands for "Bitch!" which serves to ram home the point to the intended audience.

Wolfgang: "Sergio Leone was actually approached to direct The Godfather before Francis Ford Coppola but turned it down Q.E.D.B.".

Kelvin: "No shit hey?".

q.e.d.

actually is "Quad Erat Demonstrandum" and it does mean "which was demonstrated".
Comes at the end of a mathematical proof, usually.
Maddox uses it best.

Pirate: "I claim that illegal immigrants should be paid the same wage as americans, you claim you dont want any 'spics, gooks, nips, russians' and lets not forget 'sand niggers' to 'take our jobs for less money' because they 'dont belong here'. Also you said i could 'like your balls'."
Pirate: "Wooo WOOO. Here comes the clue train, last stop is you! Now if companies like Wal-Mart are forced to pay the same wage to illegal immigrants, then any incentives these companies would have had to hire illegal immigrants if effectively destroyed."
KKK member: "Ah, i see. Will you still lick my balls?"

Q.E.D., bitch.

Q.E.D.

Certainly an abbreviation of quod erat demonstrandum but after watching, suffering through, proving thousands of proofs, a math major might just say Quite Easily Done.

The final line of many proofs of the Pythagorean Theorem.

a squared + b squared = c squared

q.e.d.

A term mathematicians like to use which literally translates as Qualified Ejaculate Dispenser, where those who have come up with an equal or better theory or postulate can join you in the lab for a celebratory circle jerk. In the film "A Beautiful Mind" this event was replaced with the scene where the other faculty members giving John Nash their pen, some after having the pen in their mouths.

Einstein was very lonely at his Q.E.D. celebrations.
