"Can you tell that I'm planning prevenge? Read my mind, yes, I'm planning prevenge At the freak show In the front row Mi amigo lost in the sound"

A guy goes to a concert with a friend, his friend goes in first, he gets left behind likely because he's either underage or doesn't have a ticket, he can't get a hold of his friend because his friend can't hear him over the sound of the concert.

"Now you know that the girls are just making it up Now you know that the boys are just pushing their luck Now you know that my ride doesn't really exist And my name's not really on that list"

The girls get in easily because the ticket checkers are likely male. The boys line makes sense in the next verse, I have no idea about the ride, maybe his friend isn't actually there but he's trying to get in anyway by lying. His name isn't on the list of people to let in.

"Fully moto On the headfo Rock the info The micro-type king"

I have no idea

I also have no idea about the Pupkin part

"Tired of waiting Tired of watching Negotiating Parading around"

He's tried everything and still sticks around either waiting for his friend or waiting in hopes of the guards softening up

So, summary: Guy goes to a concert, is pissed that he can't get in, is already planning a way to get back at his friend for leaving him behind.
