leader of the pack
(redirected from leader of the pack, a)leader of the pack
The most powerful or influential person in a particular group. I know Tommy is the leader of the pack, which worries me. He's constantly in trouble at school, and I don't want that tendency to rub off on my son. Sure, Joyce has always been the leader of the pack, but she's so bossy! I don't know if I can take much more of her dictating everything we do.
