Mam-Flu
The polar opposite to Man Flu (where a man has a slight cold but believes he's dying and can't lift a finger). Mam-Flu describes a mother who is probably suffering with the worst possible flu strain you can get but has to, and does, crack on with everyday chores/work/kids.
I've got mam-flu, but I'll still see you at work after doing the laundry, dropping the kids at breakfast club, nipping past the supermarket and getting the car in for a service.
