Stemming from the climax of the game Modern Warfare 2, the term Sheperdeded means to be killed by having a knife thrown into the eye socket. The term can also be used as a blanket adjective to describe any situation where one is unarguably fucked.
"General Sheperd was sheperdeded in the end of MW2"

"That kid got sheperdeded when he fell off the roof onto the table saw"
