When a bad guy (or an ignorant or rude person) is pwned by Sailor Moon (or a female from ages 13-21) by use of overwhelming magical force (or calling them out on their own bull crap).
I am Sailor Moon, and I fight for love and justice. I will triumph over evil, and that means you! So prepared to be moon-dusted!

Dude, that guy just got moon-dusted by that fourteen year-old girl. Damn, that's embarrassing.
