Definition

That aggressively artificial, eerily perfect smile corporate mascots and Instagram influencers deploy when they're contractually obligated to appear happy; so obviously fake it becomes a form of psychological warfare. You know the one—where the eyes don't participate.

Example Usage

She gave me that Disney smile when I asked if she was okay, and I immediately knew something was wrong.
