look up any word, like donkey punch:
 
1.
A noob who is screaming in excitement while reading some obsolete, obvious or outdated information about hacking, cracking, phreaking or just geek stuff is most likely experiencing a noobgasm. He seems to have found the greatest source of wisdom and power but in reality he just stumbled over essential information.

Noobgasms are happening pretty often on sites like digg.com.
"Whoooo MAN!!! I've found the complete documentation of the mail protocol on a page called RFC 821 on a site that looks like it has confidential information on it!! THAT'S SOOOOOO COOOOL!!!! AHHH... AAAAAHHHHHH... COOOOOL". The guy screaming and laughing and giggling like hell is having one of his first noobgasms.
