A term commonly used by our grandparents/ aunties and uncles that refers to the bathroom. It is a nice way for old people to politely make things
awkward and let you know they have to go take a
dump. Often say it in public places like Sears or the food court at the mall.
Biffie is often mistaken for some sort of cute way of saying
BFF's and Besties but it actually makes you think of grandma grunting one out in the Smitty's washroom."
"Keep your eyes out for the washroom
kiddo, Grandma had McDonald's for
lunch and it
always makes her have to go to the biffie."
