Crazy Jealous Guy: "Next Contestant" is about one of these who is always getting pissed at other guys hitting on his girlfriend or worse.
Death's Hourglass: The music video for "Savin' Me" begins with a twitchy-looking man saving a well-dressed man from walking in front of a car. Pretty soon, the well-dressed man starts to see what the twitchy man saw—numbers over everyone's heads, rapidly counting down . . . (This has absolutely nothing to do with the lyrics of the song.)
Disappeared Dad: Chad didn't know about his real father until his late teens. Mike's father and his adopted father was also this and the subject of "Too Bad"
Do Not Do This Cool Thing: "Rockstar". Seriously, it was supposed to be a Stealth Parody of the stereotypical rockstar lifestyle, with its intentionally over-the-top lyrics. Except it completely backfired.
Probably because the song does nothing to actually deride the lifestyle. Yeah they say you've got a drug dealer on speed dial or you'll be popping your pills from a Pez dispenser but at the same time, it's describing the big bus you'll be riding around in with your old guitars, getting into the Playboy mansion, or dating a centerfold model and having enough money to let her spend it willy-nilly. No one's going to deny all those things sound awesome. The lyrics are supposed to be over the top but anyone with an ear in modern society knows very well that real-life celebrities will get to enjoy these amenities and a whole lot more too.
Ignorant of the Call: In "Hero", the singer acknowledges that "a hero can save us", but that he's not going to stand around waiting for one to show up. He thus unknowingly becomes the very hero he wasn't going to wait around for, all the while denying that he's any kind of hero at all. This song is actually one of the best realized examples of this trope in pretty much any medium.
Mohs Scale of Rock and Metal Hardness: A fairly solid 5, although they can go up and down on occasion. Their ballads like "Far Away" and "Lullaby" go down into the 2-3 range, but then songs like "Because of You" and the aforementioned "Side of a Bullet" can jump up into the 7 range.
Motive Rant: "Where do I hide", 'looking for a scapegoat, long past due, walking down the aisle, staring straight at you.' The man who just killed the woman he married so he could kill her is singing about why he framed you. Just listen to how happy he is!
Oh Crap: The main characters' reaction in the last verse of "Animals." He and his girlfriend are in his car getting busy when she realizes that her dad has found them and is standing right outside. And worse, the keys aren't in the ignition because they fell on the floor while they were in the middle of it.
Random Passerby Advice: Not really 'random', but while they were arranging "How You Remind Me", Ryan brought up the idea of the musical stops in the choruses. They played it a few times that way but still felt it was missing something, at which point Daniel's drum tech said "You should do a really big stop at the last chorus". They tried it, loved the effect it had on the song, and gave him a $50,000 bonus on the spot.
