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.
'Not someone i havent met who sits behind a computer screen feasting on fucking chicken legs and shit everyday of his life'

- 'Oh that's such a Yianni-ism.'

A funny boy who likes Fazoli's food and has the best smile in the world. If you hangout with him, he will steal your fucking heart with his amazing behavior. You will be the luckiest person in the universe, if he gives you a place in his heart.
Person: Yianni Pallas
Me: Omg, my heart :(

Yiannis is a very popular Greek name, usually people with such a nice name tend to be very popular and cool but at the same time like to keep their circle small. They care and can do whatever for someone they love without second thoughts. They have gone through a lot of pain but only to become better for themselves and for the ones they love. If your boyfriend's name is Yianni you better stay loyal and show your affection and love because they like being surrounded by such beautiful feelings. If you know someone with such a nice name you better keep them close to you.
Girl1:Hey did you know my boyfriend's name is Yianni?
Girl2: wow really? Luck you!
