de-tag

The act of removing any connection one has with a ‘tagged’ photo on Facebook by clicking the ‘remove-tag’ link which appears under the photo.
This is usually done when the person tagged in the photo is drunk, partially naked, making a horrible face, or all of the above.

“Oh my gosh - James posted the worst picture of me from last night - I had to de-tag it!”
