QED

Used by pseudo-intellectuals at the end of arguments. Means "PWN3D N00B" but they pretend it doesn't because they're trying really hard to be intelligent.

Mr. C: 2+2=4
PI: You are wrong QED
Mr. C: Based on what
PI: You're dumb QED
Mr. C: What?
PI: Haha I won the argument QED
Mr. C: ???????
PI: QED

QED

Stands for "Quod Erat Demonstrandum", which is Latin for "I haven't actually proven anything, but believe me anyway."

Let 2 + 2 = 5.
Therefore, 2 + 2 = 5

QED

Used by cocky engineering I-am-smarter-than-you-and-I-know-it students upon completion of a difficult proof. To really erate the professor, add (quite easily done) afterwards.

QED

What someone writes when insecure about his abilities as a physicist or mathematician to make themselves feel smarter than they likely are. Typically used by douchebags who think they are doing something amazing by proving a problem from a textbook. Usually follows a terribly formed proof which lacks rigor or reasoning.

"x+y=2. Clearly, z=4, QED."

"You're obviously incorrect, as is seen without proof. QED"

QED

Originally Latin meaning "quod erat demonstrandum" or "which was to be shown or proven", now used mainly by physics students to insult someone when something is proven wrong or false, typically with the words "Mother Fucker" added for effect.

Ha! Your're wrong.. QED mother fucker!
