When you stay up to 12:00 PM in the next day.
How to preform a 'till the clock says FM:
1. Wake up before 12:00 PM (noon)
2. Consume energy drink of choice. (You will want to do this step. Trust me.)
3. Pull off an all-nighter
4. Stay up 'till 12:00 PM in the next day where sleep deprivation will most likely change PM on clocks to FM and FM on radios to PM.

I pulled off a 'till the clock says FM. It was brutal.
I was super tired when I tried to do the 'till the clock says FM.
I preformed the 'till the clock says FM +12 hours. AM stays AM on clocks.

Till it clocks means when it's time to finally stop. It's the maximum amount of time an activity can go on for.
