When a non-black person justifies their racism or insensitivity by claiming they have a black friend in order to prove they aren't racist.
Note: Black Friend is not a valid counterargument to accusations, thus, fallacy.
White dude: Hey, what's up my n***a?
Person: Dude, you're white, you can't say that!
White dude: No it's fine, my black friends say it's okay!!
Person: Bruh, you're using the black friend fallacy
The mythological one black friend that every group of young white males has in evey TV commercial. Most noticeable in all beer, car, fast food, deodorant and cologne commericals.
"Hey, check out that Bud Light commercial, 35 scruffy white guys in cargo shorts at a barbecue, and they invited along their TV Commercial Black Friend."
"Yep, he was just in the Taco Bell Commercial getting drive thru with 7 other white dudes."
The black person in a group of majority white people. The purpose of the Honorary Black friend is to demonstrate "diversity" in a group. They are also good for insight on black culture.
