Gibbous

A phase of the moon in which it is more than half full, but not entirely full.

The waxing of the gibbous moon bathed the courtyard in a kind of cold starlight.

Giroud

An underappreciated worker who's incredible abilities are overlooked simply because of his incredibly good looks.

Person 1: That guy is such a Giroud, he's complete trash at his job the only thing saving him is that hes sexy as fuck.

wax the gibbous

To perform fellatio during one's period. Used especially if the period falls between the first half and full moon phases.

Dude, when I get home, my girlfriend is going to wax my gibbous.
