look up any word, like sex:
(n.) One who eats acid (doses) on a regular basis.
"Dude, that kid looks like he's wiggin' out.. Someone should talk him down."

"Nah, I've seen him a lot worse than that. He's a true doser, he'll pull through."

"Bro, you sure?"

"Yeah, man. I mean, give it a shot if you wanna, but I seriously doubt he'd understand anything you say, anyways, ya dig?"

"I feel ya, man. I'll just keep an eye on him."
