Snapnesia

Snapchat amnesia; 1) when a person sends a snap that illicits a response from someone and upon opening the response, the initial responder forgets what they sent. 2) looking through some else's snaps and immediately forgetting what you saw.

"Dude what are you responding to? I have snapnesia"
"Fuck, I didn't pay attention to your story. I had snapnesia"
