Re: yes i saw the icon, but still
It's called a metaphor. It's a commonly used device in English where a word or phrase is used in a context in which it's not literally true, but where the analogy is meant to convey meaning. Metaphors often exaggerate the negativity of a given situation to make a point. For example,
"The Sports Team A absolutely KILLED Sports Team B in the big game last night. They just MURDERED them."
"Your just a grammer NAZI."
"Did you see that idiot cut me off? People like that should just be SHOT."
And, of course, the example to which you responded.
Biting the hand that feeds IT
