PI: You're dumb 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

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"

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