When a person doesn't know hot to kiss and either 1) sits there with a limp, half-open mouth and slobers all over your face or 2) puckers up and is otherwise unresponsive.
Kev: Yo man, that girl Cheyanne totally flatlined me, ugh.
Acquaintance: Ew dude, I hate flatlining! What did you do then?
Kev: I dumped her, HA!

When a friend's Facebook stops posting status updates for several months in a row. FB RECENT ACTIVITY is limited to increasingly less frequent notices that "X is now friends with ..." and an occasional "like."
I don't think I am FB friends with Nancy anymore.
Why?
I don't see any status updates from her anymore.
You're still friends with her, but she has Facebook Flatlined. I don't see anything either. Friend her on Twitter.
