- Anvilicious: The reason for the show's existence!
- Big-Lipped Alligator Moment: Mr. Budgen's demonstration of proto-breakdancing to Bolton.
- Ensemble Dark Horse: Ruby Fry, Grantly Budgen and the uncredited blonde extra teacher who never gets named on-screen.
- Fanon Discontinuity: Ask any hardcore Rachel/Eddie 'shipper. Melissa doesn't exist and the Series 4 ending didn't happen.
- Hilarious in Hindsight: The extra who looks like Mel Gibson's ex Oksana Grigorieva (on left of picture)◊, when she kept appearing during the Rachel Mason era.
- Jerkass Woobie: Several, a number of them being teenagers with a Freudian Excuse for their Jerkassery
- Although Tariq being in a young offender's institution shows he was a Jerkass long before he was introduced, he's later revealed to have been badly bullied while imprisoned.
- The programme tries to make Kyle Stack into one a few times but it's hard to make it stick when you consider that his previous actions have ranged from selling vodka at school to attempted murder.
- Justin Fitzgerald's actions throughout Series 10 are a direct consequence of the end of his parents' marriage and his mother's nervous breakdown.
- Rich Bitch and juvenile delinquent Gabriella Wark is resented by her parents for being indirectly responsible for her younger sister's death years before and is still The Un-Favourite in their eyes. The Woobie part is reinforced by her father striking her across the face after she steals a car.
- Magnificent Bastard: Max Tyler.
- Kevin Chalk when he a pulls a Batman Gambit to avoid being prosecuted for computer hacking. Which works and nets a him a job offer from the company.
- Moral Event Horizon: Max Tyler's a Jerkass from his first appearance and an adulterer to boot, but what really takes the biscuit is his physical abuse of Phillip.
- School Governor Ralph Mellor hits it when he tries to swap his daughter Flick's positive drug test for her boyfriend Marley Kelly's clean one (saving her place at the school and his reputation, and getting rid of Marley in one go), and then goes far beyond it when he attacks Marley with a golf club and later drives a mechanical digger into the school.
- Lewis Seddon crosses it when he tries to burn Jack alive.
- As does Barry Barry when he starts people smuggling.
- Small-time bullies Lisa Brown and Shaznay Montrose well and truly cross this line when they crash Gabriella's house party and utterly destroy the bedroom of her deceased sister with sadistic glee. It snaps Sue out of being an unprofessional Jerkass towards Gabriella and even disgusts Kacey who has more reason than anybody to hate Gabriella.
- Nightmare Fuel: Lewis Seddon trying to set Jack on fire.
- Lorna's ex-husband threatening to kill Sonya if she crosses him again.
- Portmanteau Couple Name: Rachel and Eddie are commonly referred to as Reddie. Kim/Andrew is known as Kandrew, but there's some debate over whether Tom/Izzie is Tizzie or Tozzie.
- Some Anvils Need to Be Dropped
- Toy Ship: Denzil Kelly and Emily James.
- The Woobie: Kevin was in care because his father abandoned him and his mother, and his mother threw him out and left him to fend for himself at the age of ten.
