Internet Service Provider. Your choice of an ISP can either be bery wise and beneficial, such as choosing SBC Yahoo! or EarthLink, or give you an idea of what Hell is like, by choosing AOL.
Words cannot describe how much AOL sucks. Worst ISP ever.

Abbrev. for "Internet Service Provider", or in my case, "Internet Shit Provider" because AOL is fucking gay.

It may not seem like much, but this word is one of the scariest things to an amateur hacker-the ISP can see through any proxy.

ISP is the provider of your internet (AOL, BT, NTL etc). AOL is a brilliant example of a gay ISP.
AOL is a gay ISP, Cause they're shit!

ISP can either mean
'internet service provider'
or
'inscribed signed photograph'.
My ISP (internet service provider) is AOL.

I sent a fan letter to Elijah Wood and got an ISP (inscribed signed photograph) back instead of just a copy.
