Facebookin' it.
Telling someone you're on Facebook like it's the most important thing in the world and you're about to drop a bombshell.
'I'm Facebookin' it, I'm about to find out my ex is married.'
'Facebookin' it, I'm gonna post this and my mom will cry.'
'Facebookin' it, I'm gonna comment on my dog's photo and look cool.'
