When your bro enters a whole new persona around girls with or without you around. Usually they become a total asshole or a completely different person. Occasionally, this douchebaggery is directed towards his fellow bros to make himself look better.
Example 1:
Bob: Why is John acting like such an asshole?
Dylan: Looks like he put on his girl facade.

Example 2:
Me and Chris were hanging out, but when Mary came by Chris become a total douchebag when he entered his girl facade.

Get the Girl Facade mug.
When a girl (typically a white, thin girl with a fringe) is high school gets away with stuff because they're quiet to teachers and asks stuff politely
Shy girl: excuse me, miss, is it okay if I do the test tomorrow at lunch? It's just, I've been ill (lie) and haven't had time to prepare, I'm sorry for the inconvenience.
Teacher: of course! No I totally understand
Other kids: ugh, I bet she's gonna cheat, just putting on a shy girl facade...
Shy girl: *proceeds to cheat on test*
