facebitch-slap
A Facebook comment so rude it makes your face feel like it got hit by a facebitch who also has a facebitch.
'You're like a broken phone. You don't work and you're always on the floor.'
'You said you'd text me. You said you'd call me. You said you'd be my friend. You said nothing.'
'You're like a bad song. You're loud and you're never ending.'
