When you post a photo or a nasty comment on Facebook to humiliate someone for doing something stupid or embarrassing.

I posted a picture of my cousin eating a whole pizza by himself and wrote, 'This man is a monster.'

I commented on my ex's wall, 'Still single? Still ugly? Still stupid?'

I posted a video of my friend falling into a puddle and tagged him in it.
