what does S4S mean on Facebook?

[Leet Banga]

S4S means sub for sub , subscribe for subscribe , so like you follow someone and they follow you , to get more subscribers on your facebook , people do it on youtube and twitter too

edit : ohk share for share thats $4$ , so someone creates a facebook page , and they want more likes , the only LEGAL way to do this is spreading your page or advertising it around facebook / the web

people use share for share like ; you have a fan page , you want morel ikes , your friend has a fn page , he wants more likes , so you share the link of his page by posting it on your fan page , and he does the same with your page , that way you kind of like "exchange likes" if you know what i mean

edit2 : just go on any page and inbox them : hey bro $4$ please ? here's my page link , ill share your page as soon as you re inbox me

btw - look for pages that have about the same amount of likes as your page , pages with 15m likes arent gonna s4s your page , they will get ripped off that way
