Seizure Porn

Very low quality streamed video captures, typically of a person or multiple people masturbating on an old school video sharing website. The choppiness and blurry vapor trails create a nauseating strobe-like effect. Very common when live personal video streaming was new, but the technology hadn't caught up yet.

Those boys were sofa king hawt, but Omegle just turned it into seizure porn.

Seinfeldianism

The belief system, worldview, or lifestyle rooted in the obsessive analysis of everyday trivialities, awkward encounters, and the unwritten social rules of life—just like in the TV show Seinfeld.

Those who practice Seinfeldianism often:
• Get irrationally upset about double-dipping.
• Question close talkers, re-gifters, and low-talkers.
• Believe “nothing” is everything.

The practice of Seinfeldianism is worldwide and spot on in most cases. Seinfeldianism will live on for ages, not that there is anything wrong with it!

seizurebait

An overedited video with an overwhelming amount of FX likely to cause someone with epilepsy an actual seizure, hence “seizure bait”.

Most commonly found in velocity edits posted to social media sites. Little to no commercial videos fit this description.

Mother: So what happened to my son?
Doctor: It may have to do with the phone he has.
Other Son: bro got into the seizurebait 💀🪫🥀
Mom + Doctor: tf do u mean
