The world's largest paint party! A rave-like dance with neon paint, loud techno music, flashing lights, and usually a lot of college kids on drugs and alcohol. Attendants wear white and prepare to be blasted with neon paint, dance like an idiot for 5 hours, and probably be groped by someone rollin hard.
guido1: SO pumped for dayglow this weekend! you?!

guido2: yeee ked the only thing is last time i rolled so hard i was depressed for 2 weeks. woof woof

The World's Largest Paint party. Pretty much a huge event holding 2,000-10,000 people all rolling on ecstasy, getting naked and touching each other while covered in paint and listening to the best house music in the world. See also: Best thing ever.

A pseudo-"rave" party at which bros fist pump, get their genitals rubbed upon by underage girls, all the while having paint sprayed on their half-naked bodies.

Now called "Life In Color."
Bro #1: Yo, I heard Dayglow is coming to our city next week, let's go!

Bro #2: Yeah dawg, I'll pick up some molly so we can feed it to some underage girls covered in paint. Then they'll grind on our dicks all night.

Clothing that glows during the day because the colors are so bright.
Beyonce was able to find her way back through the densely wooded forest at noon due to her dayglow.
