Wikipedia says, "The phrase E ticket (or E ticket ride) refers to an unusually interesting, thrilling, or expensive experience. It derives from the admission ticket system used at the Disneyland and Magic Kingdom theme parks before 1982, where the E ticket (officially termed "E coupon") admitted the bearer to the newest, most advanced, and/or most popular rides and attractions."
So I say, thanks, Wikipedia, for explaining what the hell this song is supposed to mean:
don't wanna hear it, all you do is talk about you
I don't wanna hear it, 'cause I know that none of it's true
I don't wanna hear it, I'm sick and tired of all your lies
I don't wanna hear it, when are you gonna realize
That I don't wanna hear it? Know you're full of shit
I don't wanna hear it, know you're full of shit
I don't wanna hear it, know you're full of shit
I don't wanna hear it
