When you go through a facebook photo album and tag yourself but don't bother tagging anyone else in the photo you have just tagged yourself in.
Someone who does this can be called a selfish tagger
1) Facebook: Alana has tagged herself in your album
"bitch didn't tag me or anyone else, that's some selfish tagging"
2) "oh good, she tagging my photos for me"
"nah, she's just doing herself, she's a selfish tagger"
