Slightly famous at some Brazilian forums, used when a member writes stuff horribly wrong, that is, seeming like he or she has never been to school or really suck at language (Portuguese, in that situation, since it's from Brazil), followed by the phrase "Escreve essa porra direito" (in English, something like "Write these fucking words correctly"). The guy in the pic is a famous professor/doctor/whatever in Portuguese language, and he had a tv show called "Nossa Língua Portuguesa" (Our Portuguese Language), where he'd give some tips on how to use correctly the grammar rules and all that stuff.
