Facebattle
When you take over someone's Facebook to yell at them about something they posted, like they're a complete idiot.
'You said the sky is blue? It's more like a radioactive green!', posted on my mom's timeline at 2 AM.
'You think pizza is a food? It's a crime against humanity!', typed on my uncle's status.
'You said cats are better than dogs? I'll show you better than dogs!', posted on my cousin's wall during a family fight.
