twelve o'clock flasher 

A person with no idea how to use any kind of technology. The joke is, all digital clocks, stereos, DVD players, VCRs and so on have their displays flashing 0:00 or 12:00 (twelve o'clock) because the person in question has no idea how to set the time, let alone use any other function offered.

{When standing behind someone at an ATM for a very long time} - What is taking him so long? He must be a twelve o'clock flasher..

I knew i was dealing with a twelve o'clock flasher when she put the CD in data side up.

Twelve o'clock 

Name given to girls with 10/10 asses but you never see their face. Commonly used when you and your buddy are walking behind a fine ass and you casually call out 12:00 to signal your bud.

Matt: Hey Zach, 12:00
Zach: fucking hell twelve o'clock is ahead of us again
Matt: I want to see what she looks like
Zach: That would ruin the magic of a twelve o'clock
