WASHINGTON - The tweets are extremely vulgar and graphic.
But what is more shocking is that they come from high school students in Clark County, Washington State, in the US.
The Twitter account has become such a hit among students that many parents and teachers are concerned, Seattle news website King5.com reported.
The account showcases hundreds of raunchy and downright shocking misdeeds involving sex, drugs and even teachers.
It has been gaining popularity, thanks to the users' anonymity during submission, the New York Daily News reported.
"It's like the news of the school right now," said a high school senior who did not want to be named.
"Teenagers use it as a way to give out their dirty little secrets."
School officials are worried that identifying the students will create more interest in the site.
Said Ms Debbie Tschirgi, director of the Digital Learning Services programme in one of the districts: "They are thinking about what's happening now, they aren't thinking of the implications. It's all about them being anonymous.
"Teenagers can write whatever they want to write without being identified, especially in a situation like this on the Twitter account where they can say something and don't have their names published.
"That's not uncommon. That makes them (feel) all the more brave."
She said parents should make students understand that the Internet is not the place to share stories about sex.
Said Ms Tschirgi: "It boils down to teaching kids to make good decisions about their own behaviour, their own ethics and their own personal safety."
Students from one school, La Center, popped up often in the thread, in a contest to see which school is "ratchet", meaning the nastiest or most promiscuous, a local news website katu.com reported.
Samantha Adams, a student from that school, said she was concerned.
"It's really vulgar stuff," she said.
She said she was worried what the comments can do to people's reputations, including her own.
"They don't name names, but with the tagging and retweeting, everybody knows who the tweets are about."
Meanwhile, other students said they were not too concerned by the lurid nature of the feed.
Said a student: "If it was more of people adding names (it would be a) bigger deal.
"Now that people post things that are anonymous, you can't even tell if they are true or not."
