L.O.W.D. or LOWD
A person you love who can't remember anything and calls you names that sound like they're in a f***ing fight.
My L. O. W. D. said, 'You're a f***ing idiot!' and then asked for a drink.
They called me a 'f***ing disaster' and then said I was their best friend.
I walked in, and my L. O. W. D. screamed, 'You're a f***ing nightmare!' and then hugged me.
