Kick (short for "Sidekick")
A friend/associate of a more popular, charismatic person. The sidekick gains most of his/her acclaim from merely being connected so closely to the more powerful acquaintance. Sidekicks can be found anywhere from comic books (where the term began) to the workplace and schoolyard.

Gina: The two of them are inseperable, you have to give them that.
