s/ 

Typically used in IRC or IM to indicate that the previous typo should be replaced by the correct spelling of the word.

(@SQL) fly the ver friendly skies
(@SQL) s/ver/very/

s/ 

Originates from the SED and subsequently the Perl construct for a regular expression substitution: s/REGEXP/SUBST/ will replace whatever matches REGEXP with SUBST. Commonly used in chat contexts by people with a Unix background and/or wannabe hax0rs to either correct their own previous typoes, or change the meaning of somebody else's statement.

Many people also tend to drop the final slash, either because they're lazy or because they don't really know where that expression comes from.

A: trance music sucks
B: s/sucks/rules/

4chan's "Sexy Beautiful Women" image board. Possibly the greatest place for a man (or lesbian) to be.

You can find almost ANY picture of sexy women, to almost underage to swim suits to even the (boring) beautiful face threads. I mean this from the bottom of my manly soul, they have the SEXIEST pictures here. It may take a little bit of searching to match your tastes, but it is MORE than worth it. I mean it when I say I've never faped so much in my entire life.

I'm basically a newfag to 4chan, but from what I've seen it has a fast post rate. Unlike other boards, 4 out of 5 times you will go in and come out very satisfied. Hardly any disturbing images from what I've seen.

I think the best things on the board are the high concentration of amateur pics (good for those who are tired of fake pornstar pics) and the huge, high definition pics for that high quality fapping experience. And hey, if the thumbnail doesn't look good, then you don't have to click it.

So if you don't want to pay a subscription to some expensive porn site but still want a huge variety of sexy pics of women, hop on over to /s/. Lurkers and regulars alike LOVE it and I have to admit most of the women on here are GORGEOUS.

A browser of /s/ is called an /s/perv. HOORAY FOR /S/PERVS!

Well... really, there is no such example of /s/. You have to witness it for yourself.

's 

Added to the end of a word to make a singular possesive (or sometimes a plural possesive with words whose plurals do not end with S, such as people) or a contraction with "is" or "has". Poorly-educated people/foreigners tend to use it for plurals and verbs, but that usage is incorrect.

-Correct-
Bob's cat is black.
Bob's going to the store.
Bob's gone to the store to get his cat some food.
------------
-Incorrect-
Cat's are fluffy animals.
Bob has a cat that overeat's.

/S 

The /S is known as the sarcasm switch. When you are typing a post use it at the end of your post so people know you are actually being sarcastic.

One good thing about you being wrong is the joy it brings to others. /S

It may be that your sole purpose in life is simply to serve as a warning to others. /S
