A night meant for celebrating a special occasion; hence, your wife
will wear her red fancy panties to
bed you.
This is a term introduced by
UFC Featherweight Champion Conor McGregor, who is a large Pay-Per-View draw and, in turn, a large pay day for whomever fights him (win or lose).
"I can make you
rich. I change your
bum life. You fight me, it's a celebration. When you sign to fight me, it's a celebration. You ring back home, you ring your wife. 'Baby, we've done it. We're rich, baby. Conor McGregor made us rich. Break out the red panties.'" - Connor McGregor
"I just got a raise! Now we can finally afford that Honeymoon in
Paris that you've always wanted. It's a red panty night, baby."
