There are already definitions for cleaning products that come from wives of FiFo workers.
They would place the product in the window sill, so it could be seen from the street.
OMO stood for “Old man’s out” meaning her husband was away at work.
FAB stood for “Fucking Arsehole’s back” meaning her husband was home again.
Mis is going to have to get up earlier to beat the droll irony of FiFo wives.
