Ya Moftary!
A very popular term in the internet world. Used obsessively on sites like Slashdot. Best explanation comes from an old story from 2004 that reads, in part:
“Only word I have for you is “Ya Moftary” I don’t know how to translate this, literally it means you despot, but actually it is used when someone makes a very clearly unfounded claim or accusation
As can be expected, Ya Moftary is heavily over-used.
