Snack o'clock

In an office setting, this is a time that snacks are comsumed and it is usually around 3pm.

Yo, what the hell is going on? It's half past snack o'clock (3:30) and i don't see no snacks!

Snack o'clock

the moment when you see someone very hot in person and would like to hook up with them

''Look at this hot boy over there, I really want to have sex with him!''
''I guess it's Snack o'clock.''
