look up any word, like bukkake:
 
1.
That one day of the week when everyone celebrates and honours the wonder that is bi-sexuality.

It is a chance for everyone to release thier inner self.

A time for experimentation and freedom and true equality among sexes.

Bi-fridays also accomadate threesomes or foursomes or huuuge group orgies.
Person 1: "On bi-friday i kissed this girl and guy at the same time...it was epic."

Person 2: " wow i wish i had known about bi-friday. it sounds so raucus."
