What is Hollervision?
1.
usually written in all caps, hollervision is the moment of surprise that happens when two friends run into each other at an unexpected moment and make eye-contact simulatneously in a way that both parties can see each other's surprise and thus, aknowledge each other's presence.
In a way it is like giving someone a "holler" just through eye-contact.
Woah Stevie! Never thought I'd bump into you at this mall! That was some intense hollervision we had going on eh?
