Sideliner 

AKA: "Sideline bitches", are the large number of people who sit around in the confinement of their own little worlds, picking apart the actions and efforts of others. These sub standard human beings often do not even realize that they are indeed a bunch of do nothing, whining, over opinionated, pussies, with no personal accountability or personal experiences. They tend to form their opinions based on other's words, most often provided by the media or other sideliners, allowing them to feel like they're part of the action. They will talk until the day they die, but will never be the person who actually takes part in events that are worthy of discussion or praise.

1)Dude #1: Man, this douche bag keeps trying to holler at my girl while I'm "away on business". Telling her, "if I cared I wouldn't be leaving."
Brotha'#2: What a motha'fuckin hater.
Dude #1: Ya, he is quite the sideline bitch. I think I might have to kill him. Want to help me remove his teeth and burn the body?
Brotha' #2: Fo'sho.

2) The self proclaimed "left wing", liberal elements of the United States political scene are nothing more than a bunch of sideliners. Someone should explain to them that waving signs and chanting won't stop extremist organizations from expanding and beheading them.

3) It is not a good a idea for a sideliner to approach a United States Army Ranger with his or her bullshit. It will most likely result in them getting skull fucked.

Sideliner

Someone who lives vicariously through others while being oblivious to their own failures as a human being. The kind of person to talk shit at you from behind their armed bodyguards and still have the audacity to call you a pussy. A common example is how people will call another person jealous because the person criticized a rich person for their greed. They live their lives on the sidelines because they cheer for someone and taunt others on their behalf, while receiving none of the success that that person has and ignoring the character flaws that likely contributed to their success.

Ex: Being a brokie and defending Elon musk and other billionaires that contribute to wealth inequality worldwide

Ex 2: "that guy is such a sideliner. He typed in the chat "lmao ez" even though he's at the bottom of the scoreboard and did nothing to contribute to his team winning."

Saltbae is a sideliner. He trespassed onto the field at the world cup, snatched the trophy from Argentina, and started taking pictures with it as if he was the part of the team
