The word flamboyant is such a curious word.  At its root are two terms.  The first indicates a flame.  The second means to float.

The entire premise behind the two words combined is to have an irrepressible flame which floats above repression.

Since flamboyant is usually reserved for the rich,  its meaning can be understood as a derision.   It is usually used to describe their understanding of self importance, and the subsequent display among men.

Should a Christian appreciate being referred to as flamboyant?
