being "lathe'd" by a miniature samurai with a naginata who jumped out of a bowl of corn chips;
being run over by a race car that makes the sound "TIIIIIIINES" driven by a fork;
being "arrowed" by a giant man who shoots arrows from his mouth;
The series is best known for spawning several minor memes, including "ow! my [something unusual]!", and being pwned by something with the caption "[said something]'D!", "It's over!", and others. It also makes fun of various stereotypical high-school/teen/young-adult activities, such as prom, sweet sixteen birthday parties, and Valentine's vamlumtimes day, with a gradually increasing ratio of directed, ridiculing humor to simple absurd humor.A (so far oneshot) spinoff of this spinoff was created based on the several characters named "Greg" in the series. 4 Gregs is a misadventure of four such characters who each embody some sort of nerdy/geeky/dorky stereotype.
Adorkable: What's Her Face. "Uh... hi. I like music, and um, cloth."
A Good Name for a Rock Band: Issue 12 gives us the two hipster kids who decide "She Likes Cloth" would make a good band name. Also, when the girls are forming a band, So And So suggests "Smartly Pretty", but is shot down in favour of "Kissyboots".
Against My Religion: "Thank groodness. Sweating is against several of my religions!" -Cheerleader in Issue 14
Blatant Lies: In issue 15, when Manolios Ugly One tells Dn'D Greg to not lay a finger on his daughter (or he'll gut him like a sheep), a random gutted sheep says that it isn't so bad... when it turns out to be bad.
Also, in the same issue, Arrow'd Guy claims that What's-Her-Face will come into her own in college... and then immediately afterward shoots her down with a flock of sparrows. "A new twist on an old classic!"
Bottomless Pit: Their school has one (named after its sports team, of course)
Extracurricular Enthusiast: So-and-So explains that the "Priggity Prizom" is the name of this year's prom, and adds, with a deranged look, "I was on every committee ever." This fits well with the preppy overachiever stereotype she personifies.
Eyes Always Shut: Japanese Culture Greg, befitting his otaku personality. His eyes briefly open whenever he randomly utters a Japanese word or name and assumes a Stinkoman-esque face.
Gold Digger: A visually literal example where Tompkins' mother is implied to be one, being visually based on a robotic prospector
Gretzky Has the Ball: A Scotsman caber-tosses Cheerleader in Issue 10 and is disgusted that his throw only goes 23 meters. Success in the caber toss is measured by straightness, not distance. The creators point out their mistake in the DVD commentary.
Gutted Like a Fish: Manolios Ugly One, The Ugly One's father, to D'n'D Greg: "You lay one finger on my daughter, I gut you like sheep."
Gutted Sheep:(standing nearby) It's not so bad.
Manolios Ugly One does gut D'n'D Greg eventually ("Owww! Sheep, you lied!")
Her Code Name Was Mary Sue: Creator Strong Bad inserts himself into several of the comics, most notably to make out with the beautified Ugly One.
Hidden Depths: D'n'D Greg turns out to be very knowledgeable about football. The other Gregs are surprised by this, but he explains that fantasy football is still 'fantasy'.
Mind Screw: The ending of "4 Gregs." So basically, Strong Bad was drawing the Teen Girl Squad drawing the four Gregs drawing the girls drawing the Gregs drawing the girls drawing the Gregs drawing the girls drawing the Gregs drawing the girls drawing the Gregs!
And it's a SUPER Mind Screw if you count the Brothers Chapman, so that means the Chaps are drawing Strong Bad drawing the Teen Girl Squad drawing the four Gregs drawing the girls drawing the Gregs drawing the girls drawing the Gregs drawing the girls drawing the Gregs drawing the girls drawing the Gregs!
Only Sane Girl: What's Her Face is probably the only one with any common sense. For example, she is the only one who refuses to jump into a lion's mouth for the secret Santa.
Only Known by Their Nickname: So-and-So's real name is Kristen, and the other three might be named Virginia, Joy, and Jennifer, but beyond that, their real names aren't even mentioned outside of the original email, and they're usually treated as if their nicknames were their only names: "Yes, Mrs. So-and-So... erson."
Ow, My Body Part!: A frequent running gag. Examples include "Ow! My skin!", "Ow! My hopes of reaching first base!" and "Ow! My entire life!"
Variants are used, too, such as the classic "My blood hurts."
Perky Goth: So and So adopts this persona when the girls form a band in Issue 8. "I'm going with that gloomy keyboardist look I keep hearing about!"
The Pig Pen: One Spinoff Babies episode of Teen Girl Squad has What's Her Face as a direct parody of the original Pig Pen, as lampshaded in the commentary.
The Ugly One is sometimes suggested to embody this trope in the main series. Her father seems to be an example as well, given his slovenly appearance and stained wifebeater.
The Pirates Who Don't Do Anything: Cheerleader doesn't actually lead cheers much. Whether she's actually a cheerleader is inconsistent. Lampshaded in "4 Gregs" when Cheerleader states that she's like a cheerleader in the way she dresses and treats other girls.
Police Are Useless: "Uh, yes, ma'am. We got a report of us wanting to watch the Ola Toya fight. You mind if we investigate?"
They Killed Kenny Again: Some number of the Teen Girl Squad almost always die by the end of almost every episode, the exceptions being episodes 2 and 3 and the Decemberween special. Lampshaded at the end of episode 8 where the girls have all died except for Cheerleader, with the last casualty being What's Her Face, whose upper half had been bitten off by a shark (see below):
Threatening Shark: In episode 8, What's Her Face's bass turns into a shark. "My bass feels seaworthy." And then the shark proceeds to eat most of her and take her place in the Kissyboots band.
Throw the Dog a Bone: Here and there, Strong Bad cuts one of the Teen Girl Squad a break. Examples include What's Her Face managing to get a date on (as well as survive) "Vamlumtimes Day" and a few occasions of The Ugly One having things work out for her (such as accompanying the quarterback to the end credits while the guys who pranked her get their comeuppance). Although this sometimes is done in a darkly comedic manner, such as The Ugly One getting a photo to commemorate her awesome prom experience, with the remains of her friends around her.
Title Drop: Done straight by Strong Bad at the start of every toon. Played with in issue 9:
So And So: "You guys, I think this might be the start of a kinder, gentler squad of teen girls."
Vague Age: The Teen Girl Squad are described as "teenage girls between the ages of 13 and 19", with What's Her Face being fifteen at the youngest, since she's had her license for a year (in some states, mostly Midwestern ones, you can get your license at fourteen).
The Ugly One's birthday is her "Sweet Someteenth".
"We're in eighth grade!"
"I'M FIVE YEARS OLDER AND IN COLLEGE!!!!!"
Wicked Stepmother: Judith So-and-So-erson (So-and-So's stepmom), who looks suspiciously similar to the Arrowed Guy. In episode 11, she makes So-and-So get a summer job at Shirt Folding Store.
