Flag boy 

A homosexual.

Typically a homosexual that prides himself on being gay, and needs everyone else to know it.

Those Flag boys are being far too loud.

Being overly patriotic about your country. Not hating the other countries but loving your country more than usual.

Look at that guy with the red white and blue tuxedo. Totally flagboyant isn't he?
