A resolution made for the new year, but not kept past January due to lack of commitment, a change of heart or some other excuse.
Guy #1: So many people have broken their new year's resolution by the end of January they might as well call it a 'Januresolution'.
Guy #2: Maybe people would do better at resolutions if they made new ones every month. That way, at least if they got broken, a new one would come along soon enough.
Guy #1: Yeah, but no one would bother with that.
