1. The human phenomenon and pattern of strongly advocating for, or in extreme cases, initiating the planning of a social event with zero intention of bringing said plan to fruition.
Planbitiousness (noun) usually occurs on Mondays when the promise of a new weekend evokes a false sense of capacity for activity. This temporary fervor for human interaction typically dips midweek and then the inverse intensity is applied as the "event" nears; with equal diligence, the human will attempt to stop or avoid the event by any means possible.
I got a little planbitious last night and planned 6 consecutive brunchilates classes. I'll have to put my dog down on Saturday.
