I do the same thing, just a little more offensive. My mom is anti gun, and I said I was pro gun. We got in a simple debate, and then her debates turned into anger and she went, "And now were eating everything?? All the chickens will be gone if we keep doing this!!" And I responded, "Mmm, yummy chicken." My sister was like, you don't even eat meat. So then my mom went, "AND THE CHINESE PEOPLE HAD EATEN EVERYTHING!" And instead of saying "mm, yummy chinese food", I instead said "yummy chinese people".
Now, every time I see a Chinese person I say, "yummy chinese people". And then I continue to say in a 'creepy' voice, "I've eaten you, now I have the virus." And if the food that is given to me is made by a Chinese person, I say, "This food tastes familiar."
Yes, this may sound mean on my side and that's why I don't say it on KS because you may not get my joke because you weren't there but I do say this a lot XD
*avoids the fact I'm calling my grandmother a yummy Chinese person*
Don't call me out it's just a inside joke between me and my mom and sister
