roll-over face 

The face a woman makes when, while sleeping and spooning, she turns over to reveal an ugly face. Possibly with her tongue out and drooling.

Yo, man, if your woman has a roll-over face, she got to go!

Facebook rollover 

When people start making the same comment which has already been made regarding a Facebook item because they didn't bother to "View all" the item's contents and therefore negleted to see that their comment is redundant.

Tim: Why do people keep commenting that they now have that "song stuck in their head" regarding that link I posted about Vanilla Ice?

Dan: No one bothered to hit the "View all comments" link so now you're getting Facebook rollover.
