The fact of device working perfectly always except when demonstrated for an audience. Something unexpected that goes wrong only when someone else than just oneself is seeing.
Somewhat connected to Murphy's law.

The Damon Effect 

When a person (usually a boy) puts another person (usually a girl) high up on a pedestal. Usually resulting in them ruining themselves over the fact that the person most likely isn’t interested and ruins their relationship with them and/or ruins their relationship with their friends, significant other, etc.

Jordan? Yeah he’s in the Damon effect with Hailey.
