1. Someone with an excessive, pathetic allegience to an organization or person, usually a boss. A boot-licking toady will unflinchingly cater to his master's every wish irrespective of propriety, other people's feelings, or even ethics. Having little or no identity of his own, he will emulate his master in almost every aspect, from appearance to speech and mannerisms.

2. A bobbleheaded sycophant.

3. A mini-me brownnoser.

Someone people turn to when they're sad who makes them feel better.
