Facebookin' it.
When you check Facebook so fast it's like you're trying to steal a cookie before your brother notices and yells at you.
'I checked Facebook real quick, now I'm commenting on my teacher's post.'
'I Facebookin' it before my math test and wrote '2+2=5' on my status.'
'Facebookin' it, I misspelled my name and now my whole class is laughing at me.'
