sideline 

To sneak up behind someone in the bathroom and devilishly ass ram them as they are bending over to lay down Toilet paper.

Yo did you hear how Jessie sidelined that kid during intermission of the Celine Dion concert?

sideline 

In sports, the people on the sideline don't get noticed, they're in the background.

Don't let the whining mollycoddle fool you, she got as much sports playing time as a kid as any other kid, her mother and father watched as many of her little league games as they did those of their male children, and she was the kind of person that liked attention so much she would try to walk over anybody she thought was weaker or more passive than her to get it. If you listened to her lies, you would think her mother and father didn't even notice her and that she had to do 10 times as much to prove she was just as worthy as a boy, when really the narrative is a means to an end, a way for her to keep getting the attention she was always accustomed to getting since birth because she was a bully (the kind that bullied due to too little discipline instead of too much). It's everyone around her that always had to prove that they were still worthy of anything once she arrived somewhere, it was everyone around her that had to prove they were not already obsolete, outdated, phased out, or useless (and ready for demolition). She was Buzz Lightyear, her mother's new flying toy. How could anyone not be obsolete when Buzz Lightyear came around? It mattered only to Buzz Lightyear who was on the sideline.

sideline friend

A friend that is well liked by friends but doesn't get asked to hangout or get invited to things and is left on the "sidelines"

She says she likes me but never wants to hangout with me, I feel like a sideline friend.

Sideline Friend

You're the friend that can never make it to events and you often watch your best friends fall in love leaving you for a third wheel position. Then when they break-up, you're caught in the middle of friendships usually making you chose a friend over the other. You've lost a majority of your friends because they either moved or you lost contact with them. You're actually lonely although you have plenty of friends. You're not really open and you fear to lose your best friends or you don't want to get close and then lose them. So now you just watch from the sideline as sort of a cheerleader. You're close enough to be supportive and far enough to watch everything being played out and find your position among your friends. In all honesty, you want the hugs, hangout days, birthday parties, and movies days. But you don't want to deal with the emotions of losing them either to death or a break-off. You don't like taking risks in relationships which most likely is the reason you're single. A lot of girls/guys like you and you even have one person desperately wanting to be with you. But from you first Crush/Relationship you learned a hard lesson of following your head and not your heart. So From the sidelines, you will watch until the opportunity comes, as the Cheerleader.

I love my best friends but I can never make it to their performances. I hate being one the sidelines but ig I gotta stay.

Her and zack are back together now, time to get new friends I guess.#Sideline Friend
Okay...they both told me the problems they had with each other and how bad it is to be friends with them. #Sideline Friend
