A defense mechanism usually used by women, to create a illusion that she is a prude. Often used when with a large group of people, but once her friends leaves the shield is down and becomes a slut
Guy 1: Dude she is such a prude, she won't even kiss me

Guy 2: Man, you have to seperate her from her friends, its the prude shield man
