Crack O' Lantern 

The smile that a longterm crackhead/cokehead displays due to missing teeth. The remaining teeth are spaced out with the gaps from missing teeth very obvious, thus resembling a classic Jack O' Lantern carved mouth.

I once worked with a super cokehead, Andycaine, who has a Crack O' Lantern grill.

Ash-O-Lantern 

An Ash-O-Lantern is a person who loves Ash Horne from The Midnight Beast an unbelievable amount.

A lot of them try and spread him around to help him become more famous :P they obsess over random videos of him also... Some find a little (or alot) too much info about him...Some can be seen as freaky .. others just really really reeeeally like him.. all in all they love Ashley Horne.

They can be seen on all Ash related message boards.

Girl 1: Do you consider yourself an Ash-O-Lantern?

Girl 2: Well last Saturday I spent hours trying to find a leather jacket like Ash's and got my brother to buy it and wear it... so .. you could say that...

Boy: Hey guys!

(gets ignored)

Girl 1: Oh man did you see that video of him dancing!! I tried to learn the dance ... I guess I be an Ash-O-Lantern too..

Boy: guys? hello?... (hangs his head in sadness)

premature ejac-o-lantern 

To become overly excited about Halloween and making a jack-o-lantern too far in advance, thus allowing the pumpkin to rot and leave behind an unexpected mess that is embarassing to clean up. Usually happens once a year.

"Hey man, did you hear about Kory?" "I guess he premature ejac-o-lanterned all over the kitchen counter. He had to hurry and clean it up before his roommates got home."

Crap-o-lantern

A Jack-o-lantern, carved and left by someone's front porch, that is subsequently opened and defecated in by passers-by sometime around the Hallowe'en season. This prank was notably featured on Robot Chicken, but has been performed in various other circumstances. More than simply smashing pumpkins, giving someone a crap-o-lantern is considered one of the most profane Hallowe'en pranks in existence.

Honey, I just went out to the porch, and the neighborhood hooligans turned our jack-o-lantern into more of a CRAP-o-lantern.
