Xactivity

Pronunciation: /ˈzæk.tɪv.ɪ.ti/ Noun (informal) 1. An action or series of actions performed with the confident belief that one is exhibiting a heroic or impressive demeanor (akin to Batman), while in reality appearing notably less dramatic or heroic (closer to Robin). 2. A comically overconfident display or pursuit, often fueled by self-assurance that exceeds the actual effect. Origin: Early 21st century (humorous slang): from the proper name Xac, referring to a person who habitually undertakes such endeavors, plus the English suffix -activity, signifying an action or undertaking.
