People who claim to be a "friend" but act like more than a friend when it's convenient...but quickly become a friend again because they can't get past their commitment issues. Believe it or not, this is not about me because I'm in a pretty cool relationship with someone who's proud be my man. My bro's "friend" has major issues.
People who try playing with you by cracking a personal joke after just meeting you. Some of that isht (ie "You must work for Country Crock - spitting out all of that butter from your teeth in those tubs.") isn't funny when you don't know that person.
Even worse, the dummies that don't have sense to think before speaking to those they don't know.

I had to hold my cousin back from smacking up my bro's friend.
Can you tell that all of this stemmed from one day...?
