Virtually anything Yianni Boutsokefalokopoulos says, however this term can be used for anyone. He is known for being completely
politically incorrect, blunt beyond belief, borderline obscene, offensive, and yet at the same time as honest as humanly possible. Many
appreciate the sincerity after the initial anger has died down. If they don't appreciate it, they're simply in denial.
The main point of the Yianni-ism is the complete lack of
giving a shit, despite a good/bad/punch-in-the-face type reaction.
