The person in a group of two that is the lesser. He/she is typically lacking that umph that the hero gives, and gets stuck with red tights. Many sidekicks took too long to develop their social skills, and were major douche bags.
Sean: "Robin is the perfect sidekick. He just sits there in red tights while Batman jumps and does ninja stuff."
Larry: "True that."

sidekick: A new item on the market recently produced by red rhino fireworks. It is more powerful then a firecracker but very loud and pretty much the legal version of the m-80. (only sold at the indian reservation)
hey, lets go get some sidekicks from the reservation and go blow up some coffee cans.

the t-mobile sidekick is just about the best phone ever. If you own a sidekick, you are most likely to be envied by your peers. You can do everything on this phone. I mean EVERYTHING. Text, surf, Im, take notes, take pics, play games, listen to music. If you have a sidekick, your automaticly the shizznit. This is a phone favored by scene kids and rockstars.
Kid1: omg is that a sidekick?
Kid2: uhhh yeah...
Kid1: 3?
Kid2: yup
Kid1: ugg I'm so jealous
Kid2: I'm sorry
