Here is one that I have
Those upper middle class, white, suburban children that act "gangsta".
Don't even get me started on this. I live in a middle/upper class community, and everywhere I look at school are people trying to act like a gangster. One kid actually says things that rappers say, or sing, in the middle of math. And they end all of their sentences with a word like "yo". It ticks me off.
I wish I could pop them in the mouth.
