protervitās

The petulans (σπαταλῶν) sins against modestia through wantonness, raillery, and needless attack; the procax, through importunity and boisterous forwardness; the protervus (from proterere? or ταράξαι?) from impetuosity and haughty recklessness; the lascivus, through unrestrained frolicksomeness and inclination for play. Hence petulantia has its foundation in aversion to rest and quietness, or in the love of mischief; procacitas, in assurance or complete impudence; protervitas, in a feeling of strength, or in insolence; lascivia, in high spirits, or the want of seriousness. (iii. 40.)
