coxcombry

A behaviour or manner that is characteristic of a coxcomb; a foppish behaviour.

He was clean shaved; clean shaving is a favorite coxcombry of the deacon class.

Behaviour or airs characteristic of a coxcomb; foppishness.

His manner was perhaps the more seductive, / Because he ne'er seem'd anxious to seduce; / Nothing affected, studied, or constructive / Of coxcombry or conquest: no abuse / Of his attractions marr'd the fair perspective, / To indicate a Cupidon broke loose, / And seem to say, "Resist us if you can" -- / Which makes a dandy while it spoils a man.

He paused, grimly regarding it, while a dash of pleased coxcombry seemed to mingle with the otherwise savage satisfaction expressed in his face.
