The level of shit a bloke gets into with his wife.
Generally occurs after a night out
on the booze with his mates and he gets home very very late.
Shitometer readings -
10/10 - roaring, you are
in the doghouse!
5/10 - usually still at this level 5 days after peaking at 10/10.
3/10 - simmering and ready to erupt at any tick of the clock, the shitometer never goes lower than 3/10.
