Those who claim to be an insomniac largely fall into two distinct categories.
Firstly, those who are genuinely and tragically afflicted by the inability to sleep.

Secondly, the fucking idiot emo wannabes who simply stay up past their bed time whining on myspace rather than actually trying to sleep.

Around 99% of all teenagers who claim to have insomnia are lying, attention seeking fucksticks who are so uninteresting, they have to make up something like insomnia to give them some kind of "edge".

Most people with insomnia will not discuss it as lightly as those people who fake it.
Friend: Where were you this morning?

Emo Twat: Dude I'm a fucking insomniac, I can't fall asleep until like 4am every night. It's so lonely, and yet beautiful at that time, I just feel so at peace with the world.... oh yeah, here, I wrote this poetry for you.

Also a person who has a sleeping disorder known as insomnia. I have insomnia and i only get a little more than an hour of sleep a night.
Im having trouble trying to sleep
Im counting sheep but running out
As time ticks by, still i try...
*then later in song*
My mind is set on overdrive
The clock is laughing in my face
A crooked spine
My sense is dulled
Passed the point of delerium
-Brain Stew-Green Day
