beater o'clock 

When it is the time of day to put on a beater (the shirt, not the car).
It can be any time of the day or night.

"What do you reckon Sam, just about beater o'clock?"

"I reckon it is, mate"

5 o'clock beaver 

Short pubic stubble on a girl's vagina that has grown since the morning shave, usually seen on a prostitute after an honest day's work

Man: Rough day at work? You've got that 5 o'clock beaver.
Prostitute: Tell me about it.
