Canadian First Nations (Native American, Métis specifically, Native mother, Greek father) here. I'm overly stoic to the point of being widely considered unapproachable by the standards of the white devil (I jest, you crackers are all right for the most part), dislike physical contact with people I don't know (I don't care how impolite not shaking hands when you meet someone is in your culture, I'm not fucking touching you when I don't even know if I like you yet), have long hair (about 20 inches now, worn in a loose ponytail as opposed to a braid though), drink tea fairly often, and I refer to macaroni & cheese exclusively as Kraft Dinner, regardless of whether it was made by Kraft or not.
I break the other local stereotypes across the board though. I don't consume any narcotics, am a hard worker, am very good at managing money, am generally considered to be above average in intelligence, have a well-developed vocabulary, do not speak like a Cholo, do not dress like a cowboy or a hip-hop/rapper wannabe, am taller then the national average at 5'11" (177cm) in stark contrast to the other shorty Natives around me that have to look up at me when attempting to speak to me, I dislike game meat with the exception of caribou, I'm very liberal, I fucking LOVE science, technology, and progress in general, and I can grow facial hair that doesn't make me look like a pedophile.
I don't know enough about Greek stereotypes to be able to comment on that half of my DNA unfortunately.
