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*
