This is an absolutely baffling term originating from Marvel's New Warrior's comic reboot. The experimental internet gas gave a character called Screentime (a meme-obsessed teen superhero - literally) his special powers after his grandfather made the gas. This is a legit Marvel creation.
What.
What.
"A Meme-Obsessed super teen whose brain became connected to the internet after becoming exposed to his grandfather’s “experimental internet gas.” Now he can see augmented reality and real-time maps, and can instantly Google any fact. Does this make him effectively a genius? He sure acts like it does."
