A Spedtismo is someone who's sped beyond comprehension. There are many factors to someone being a spedtismo, such as someone's eyes being placed diagonally.
Example 1:
Carl: Yo, look at that kid over there in the lunch line.
Fred: What in the fuckaroo? That dude is blowing snot bubbles from his mouth with a 2-inch gap between his eyes! Fuckin' spedtismo, bro!
Example 2:
Kevin: The LGBTQ community is the best community ever!
Alex: Shut the fuck up, you brain-dead ass spedtismo retard.
