Do I need to lose arm flab?

My friends keep telling me that I should lose arm flab to look better. The problem is that no matter what I try I just don’t seem to be able to get rid of this stubborn fat. My mother also has flabby arms, so I wonder if this might somehow be a genetic condition. Maybe I just have to live with this and accept my arms the way they are. Actually, I do not have a problem with this, but if your friends are complaining all the time then you will think about it nevertheless. I think I have two options now. I could try finding a better arm flab exercise. Or I could try finding better friends.
