Sir? Looks like your nuclear core is overheating...

MELTDWN is from Tim B. I'm guessing this person is either really into nuclear accidents, or throwing tantrums. I learned on wikipedia that a tantrum is officially:

... an emotional outburst that is typically characterized by stubbornness, crying, screaming, defiance, angry ranting and a resistance to attempts at pacification. A tantrum may be expressed in a tirade: a protracted, angry, or violent speech.

Or in this case is expressed by: a horrible vanity plate, a giant spoiler, and a Chevrolet logo that is making my eyes burn.
