Any period of time where you and your friends go out without initial purpose or expectations. Usually in the early hours of the morning or late at night, side quests last as long as everyone is still out away from their home, dorm, or common meeting space. Side quests usually happen after a "main quest," scheduled hang out or party and usually feature less people than the original main quest.
"I'm bored but idk what to do... wanna just go out?"
"Hell yeah man let's go on a sidequest!"
A group of people that rolls 600 pounds deep, which is really no different than if one person acted like the 600 pound gorilla all by themself, it's just bullying spread around a group to fuck with somebody. Just like each person has an asshole, and to some degree is an asshole, a collective 600 pound gorilla has a collective asshole so that no one person has to take responsibility for being the asshole or the one who said this or that.
The collective 600pound gorilla was punching its chest, showing who the alphas were.
