When you and a girl love each other, are with each other when you can be, but are NOT bf/gf.
It's like 'an affair that's out of time'.
The game was supposed to end, but it's not over yet...
Like injury time in football. The game clock says 0:00, but you still get to play.
I don't see her much, but we've still got that connection... she's my Overtime Girl :-)
