Tuxedo Night is a night hosted by Barney and Ted in Definitions.

Although it is made out to be a regular occurence, it has only been seen once. Marshall has expressed disappointment that Barney and Ted haven't ever invited him to Tuxedo Night before, and even went so far as to have his own Tuxedo Night without telling Barney and Ted, to let them know how bad it feels to not be invited.
