Why should you never let an Ethiopian give you a blowjob? They'll eat your dick. Literally.
Are you implying that Ethiopians are cannibals?
Yeah so what? Ethyopians are all poor and starving. They don't have food.
It's not okay to demean Ethiopians by suggesting that they are all starving to the point that they would result to cannibalism. Instead, you should take time to learn about the country and it's resources. This will be helpful toward making more appropriate comments.
