1. Describes what happens when a person freaks out, cracks, loses control of themselves. Life - reality at large- becomes overwhelming. They just can't deal with it all. The person may act out, withdraw, become emotional, run, etc...
"I was sick and on this one day I had an exam, an essay due, a news print deadline, multiple other commitments, 3 people hogging my limited time, others screwing with my head plus, life outside of college was spiraling out of control. I became overwhelmed and went into meltdown." --If meltdown happens to you or someone you know, just remember; It's not the nicest thing, but it happens. Step back & regroup. That's all you can do.

Essentially a bicycle which has fallen apart and is no longer rideable, but due to desparation it is used regardless. Original meltdown was manned by Plodman.
To qualify a bike as meltdown-esque, it must have at least 3 of the following:
- Brake cables snapped/no break mechanism
- No ability to shift gears
- A wheel so buckled you could classify it as voluptuous
- A warped and bent frame that is hardly able to support to weight of the rider
- The name of the rider scrawled upon the frame in permanent marker

Random chugger: "Hey Mox, did Plodman ride the meltdown tonight?"
Mox: "He tried, but he lost it's handlebars on a chugquest home last night. Let's get some chicks."
