I have trouble with lyrics

I have had trouble understanding what singers are saying for my entire life.  It's not that I don't get most of what they are saying.  There are just lines that I struggle to understand.  It's not too bad, because I'm usually in the car by myself when I sing, or sometimes I sing without thinking about it with Sarah in the car.  I refuse to sing in front of anyone else.  But the problem arises when Sarah is in the car with me, because she doesn't struggle to hear the lyrics, and she also doesn't struggle to laugh at me when I'm screwing up songs.

One group that has always given me trouble has been the OC Supertones.  I have always loved their music, and I inevitably end up singing along with it, but there always seems to be at least one song per album that trips me up.  Their new album just came out yesterday.  As usual, there was one song that I couldn't understand.  I knew what I heard, but at least this time, I knew I was wrong.   I even sought counsel from my wise wife, but she couldn't decipher it, either.

Here's the song.  You can jump to 1:12 in the song and listen for ten seconds and see what you heard.  I'll tell you what I heard after the video, though, because I don't want to sully your ability to hear for yourself.  Ready?

What did you hear?  Here's what I heard, versus what was actually said:

What I heard: We’re boppin’ like a blitzkrieg, pilin’ in the backseat. Party till my butt cheek generates steam heat. No rows no seats, everybody on your feet, and smash it up! Smash it up! Meet me at the downbeat!

What was really said: We’re boppin’ like a blitzkrieg, pilin’ in the backseat. Party till were fa-tigued.  Generating steam heat. No rows no seats, everybody on your feet, and smash it up! Smash it up! Meet me at the downbeat!

Samsonite!  I was way off.
