(Verb) To inadvertently DDoS attack a website due to sudden interest, often caused by a reccomendation from someone with many online followers or fans.
Coined on the 26th August 2011, when popular indie games developer Notch (Markus Persson) directed his 300,000 or so twitter followers to visit the website of Grimrock, another indie game, almost immediately crashing it.
Notch: Check out this awesome game! *trollface*
Me: Man, that website is gonna get Notched.
