Definition

Someone who fundamentally misunderstands basic Snapchat mechanics—specifically, someone who thinks the fire emoji is unlocked by a 100-day streak with one person, when it actually represents consistent daily messaging. Basically, someone confidently wrong about digital culture.

Example Usage

He tried to explain Snapchat streaks to me and I realized he's a total Leo who has no idea what he's talking about.
