The word “newsflash,” like the phrase “no offense,” is an early indicator that what follows is probably going to be something pretty bitchy. Unless, of course, you’re watching TV news, in which case the word “newsflash” more likely heralds the announcement of a hard-hitting segment about the household product in your kitchen that could be killing your children. Either way: proceed with caution.

Exhibit a) from roommate to roommate, Chicago

Exhibit b) from mother to daughter, Irving, Texas

Exhibit c) the pointed use of song lyrics in a Facebook status update

Exhibit d) stating the obvious

“My roommate thinks I took her dry erase board when I was 40 miles away the week it was taken,” says an anonymous college student in Tampa, Florida. “She has been leaving me notes like this ALL YEAR.”

God help our poor submitter, but I’m nominating this crazy rainbow of a note for the passive-aggressive hall of fame. (Prize: a year’s worth of anger-management therapy?)

Curse as much as you want, dude: you’re still bitching about body wash. (Personally, that’s what I’d call a gamekiller.)

This fridge saga (from a Boston-area university lab building) comes to us with a confession on the part of the anonymous submitter: she started it, sort of.

It all began when she discovered that her salad dressing had been mysteriously disposed of. Sad that she had to eat dry lettuce for lunch, she left a note (1) for the black hand responsible “in the least bitchy way I knew how.” She didn’t realize that her soundoff was actually a declaration of war.

Adds our submitter: “Needless to say, I think we have all been spending a little too much time in the lab.”

Ruben in Pregon works for an Apple reseller where the managers like to fire up the sales team with little competitions. (iPhones don’t sell themselves, people! For that, you’ll have to hold out for version 2.0.)

When Josh, the store’s very own Dwight Schrute, was pronounced the winner of a recent contest, things unfolded pretty much the way you’d expect.

The only person more universally reviled than the office suckup? the new guy, of course.

Says Ruben: “Most of us are real sticklers for keeping track of new product, but recently we brought on this new guy, Victor, and he hasn’t been doing too well.” Ruben came into work one day to find this MacBook battery on one of the tech benches, along with these notes that explain the entire story in just nine words. (And three question marks.)

Ruben says this pwnage became less hilarious when Victor actually did end up getting fired. “Awwkard!”

Our anonymous submitter in California was having some issues with her roommates not washing their dishes. “It got so bad that I picked up what I thought was a black bowl…only to find it was white and covered in ants,” she says. When asked to clean up after themselves, the roommates responded with a note calling her a bitch. Then came this one — accompanied by someone peeing in her shampoo.

Adds our submitter: “I moved out not too long after that.”

Brandy in York Haven, Pennsylvania forgot to put water back in the fridge, she says, “and my boyfriend likes his cold water.” Yikes.

Also note the list of tasks for Brandy and her boyfriend at upper right. Um, so much for challenging gender stereotypes at home, huh?
