Look after your brother, ya idjit.
"Idjit" is an affectionate, but exasperated, appellation usually applied by Bobby to Sam and Dean. It has become something of a catch phrase, and Bobby's use of it is imitated by Crowley in 6.04 Weekend at Bobby's. In 7.10 Death's Door, Bobby's dying word to The Boys is "idjits", said with a smile.
Following Bobby's death, Garth steps into his role, adopting a number of his mannerisms including using the phrase "idjit”.
Idjit = idiot. It’s a Southern thing.
Bobby: Just ... look out for your brother, ya idjit.
Bobby: Oh, you mean my legs. Well, I'm just weepin' in my Haagen-Dazs. Idjit.
- Dean jumps up, clicking his heels in the air.
Sam: It'd be just like when you turned the knife around on yourself. One action – just one leap.
Bobby: Are you idjits trying to kill me?!
Crowley: I'll give it right back.
Bobby: You think I'm a natural-born idjit?
Crowley: Save you the recap. In fact I'll do the shorthand for you. (points at Bobby and speaks in a mock Bobby voice) I want my soul back, idjit.
Bobby: Oh, you two go on ahead. You got this covered. I, uh, forgot I promised that idjit Rufus I'd work the phones for him, so...
Rufus: Nothing here, either. You call Willie?
Bobby: Of course. You think I'm an idjit?
Castiel: Are you sure?
Bobby: Well, we can't just strand those idjits in Deadwood, can we?
Sam: Wow. Talk about talking out of your butt.
Bobby: Yeah. Just hurry, you idjit.
Bobby: Lovecraft tried to jimmy a damn dimensional door. Idjit.
Dean: What, you want to do couples’ yoga, or you want to get back to hunting the big bads?
Bobby: Shut up. Idjit.
Bobby: (on phone): No, you idjit. It means you two got to get the hell out of Dodge. This guy hones in on people who feel guilty. Who does that sound like to you?
Dean: (on phone): Are you even working, Richard Gere?
Bobby: (on phone): Shut up, you idjit.
- Bobby writes “45489” (one number less than he wrote on the piece of paper earlier) on Sam’s hand while breathing heavily with the effort. He smiles slightly at Sam and Dean. who lean closer to him.
Ezra Moore: So, spill already. What bucket of syrup did you two idjits step into?
Bobby’s ghost: I’m right here, you idjit!
Bobby's ghost: Idjits.
Bobby's ghost: Hey, hey, go easy, you idjits. Sorry for the jump scare.
Bobby's ghost: Is that the best you can do? Idjits.
Garth: You're such an idjit.
Dean: Idjit's supposed to be used angrily. Okay? Not happy. If you're gonna butcher it, don't say it at all.
Garth: Not me, man. I let all that stuff go with the help of my yogi, my Sega Genesis. And you should, too. You can't change the past, amigo. Now, there's something I want to say to you. Stop being a idjit! With Bobby dead, you and Sam are all each other has. And that's not so bad, man.
Bobby: Well... I'll, uh, do my part, get to the end of this, but... I ain't exactly the retiring type, so, you idjits figure out a way to spring me...
Bobby: Oh, you mean like the way one of you idjits does some "bass-ackwards" crazy thing to beat death, like sell your soul?
Actress playing Bobby: You, idjits! You, idjits. You are idjits.
Castiel: Dean has given up.
Bobby: And you idjits haven't.
Castiel: Would you?
Bobby: Hell, no.
Rufus: Would it kill you to at least wash this damn thing? It smells like roadkill casserole in here.
Bobby: Just shut up, ya idjit.
Bobby: Are you gettin’ soft on me, Rufus?
Rufus: Yeah, soft this.
- (Rufus flips his cell phone shut.)
Dean: Look I got a possible lead on Lilith in Maine. But we're on a case in Reno, I texted you the address, so if you're done sitting on your ass…
- (Bobby stares at his phone, dismayed, flips it shut, and tosses it onto the empty seat next to him. He starts the car.)
Bobby (Apocalypse World): We took a vote, see who was idjit enough to go off to this Other Earth with you.
Bobby (Apocalypse World): Let me get this right: the ice caps are melting, a movie where a girl goes all the way with a fish wins best picture and that damn fool idjit from The Apprentice is President?
Bobby: And you call where we come from Apocalypse World?
Sam: Good point.
Bobby (Apocalypse World): Well, we don't need permission to look at houses. Especially when the main office is run by a bunch of idjits.
