Alternatively '(the) end of Internet' or '(the) Internet is over', and optionally suffixed with 'everyone go home'. Derivative of 'thread over'. When quoting someone, used to express that the channel, forum, or Internet in general cannot conceivably contribute anything as clever, funny, or insulting as said message or post. Reserved only for the utmost win.
For example, if a troll were to be gloating about his or her anonymity, and someone (possibly a real life acquaintance of the troll) were to post a Google Maps satellite image of said troll's home. The post with the image would be quoted and replied with 'Internet over', albeit aforementioned variations.
