A Native American tribe that once was (and still is) very powerful and insightful. They have four reservations currently in the U.S. and Canada. One reservation is located in Browning, Montana and is the most beautiful place on the planet. The other three are located in Saskatchewan, Canada. The Blackfeet are very proud and very funny. And, it would be best if you didn't get in a fight with a member of the tribe (trust me).
Stereotypical white guy: so, like, are you a Blackfoot?
Stereotypical Blackfeet guy: fuck, no, you fucking idiot. I'm BlackFEET. FEET! Now get the hell away from me, dipshit, or you won't live to see tomorrow!
Blackfeet, or blackfoot is a derogatory term for the French, referring to their muddy feet after fleeing from battles in World War One.
"Hey, I'm French, too!"
"ZOMG U BLACKFEET!"
