Legal Goggles

When a person finds every young girl to be at least 18, regardless of the obvious, they are said to be wearing their Legal Goggles.

Often used to justify potential actions with said jailbait.

Matt: Dude why is Mike hitting on my little sister... Shes in middle school...

John: Shit I think he has his legal goggles on, he probably thinks shes 18. I´ll take care of it.
