HFD

Heavy flow day (usually the first or second day of a woman's period).

"You got any chocolate? It's HFD today... maybe it will take my mind off these cramps."
"Shit... HFD is coinciding with Chelsea's sleepover... I hope I don't leak all over the sheets."
"I'm preparing for HFD" *stuffs bag full of tampons, pads, menstrual cup, painkillers and chocolate*

HFD Blitz

When a large number, usually more than 3 Houston fire ambulances transport to the same hospital. Resulting in hospital staff being overwhelmed.

This works vice versa with houston fire trucks.

Nurse: wow! That’s a lot of patients in the ED!

Random firefighter: Yeah! Must be the good ole HFD blitz in action again!
