Twittletale 

Someone who, when a person is subtweeting, tags the person being talked about into the thread (usually for the purpose of siccing them/their followers on the subtweeter).

Some twittletale tagged my thread and now I have a bunch of randos clogging my mentions calling me a cuck.

Tattletale 

A tattle-tale is a (sort of) righteous person who complains about you every time he catches you doing something you shouldn't do. They are all very annoying.

One day, a tattletale called melvin sneedly caught bob the bully putting a stinkbomb in the teacher's desk to prank him.
He ran to the teacher's office to tell on him. Don't be such a tattletale! screeched bob. Or prepare your a**s later!! Of course he got worse punishment for using a vulagarity. Arrrghh!! Thought bob as he got caned by the teacher. I'm going to get melvin later and punch the daylights out of him! But that's another story.
The end.

Photoshop Tattletale 

A person that feels the need to point out that Photoshop was used on an image, no matter how super cool or hilarious the results may be. The fact that people ALREADY KNOW that the image is OBVIOUSLY Photoshopped does not discourage them one bit. They think this makes them seem smart or computer savvy.

"Dude, no way is that rooster THAT big, it's Photoshopped...!" "No REALLY, seven foot roosters aren't real...? I had NO idea, quit being such a Photoshop Tattletale, you're spoiling our fun..."

Tattletale 

1. A person (especially a child) who informs the teacher/parent/guardian about others

"John Doe is having a seizure" NOT A TATTLETALE
"Mary Confoogi caused John Doe to have a seizure" IS A TATTLETALE

While some kids think telling is advocating for themselves, it really isn't.

Mary Confoogi is a tattletale
