Is it normal i hate my best friend's friends?

I've known my best friend for about 5 years, but didn't actually start hanging out with them until about 4 years ago in late 2012.
Our friendship seemed to be getting stronger as time went on, but then it all kind of came to a stop when I had to switch schools due to all the bullying I was receiving.
From that time on, we both started to try and make new friends, but at the same time we both made huge efforts to keep in touch and as a result remained best friends. I hadn't really made all that many (any) friends due to, in all honesty, not really seeing the point in it. On the other hand, she'd made loads of other friends.
The issue at hand is, I just don't like her new friends. It's not that I'm jealous of them, I hated them far before they became my friend's friends. I just, don't like them as people - I don't like their personalities, their senses of humour and the way they seem to make my best friend act so differently. She seems to act like such an idiot when around them, their jokes ranging from making "UUUGH" sounds, so spouting "OKAY" in high pitched voices.
Is it normal for me to hate my best friend's friends?
