puerility
Immature conduct displayed
Puerility is childishness or immaturity, especially in someone old enough to know better.
The word carries more contempt than "childishness"—it suggests behavior that's not merely young but foolishly so: The puerility of his jokes embarrassed everyone at the dinner party.
The adjective is puerile.
