The terms “Google Is Your Friends” or GIFY is extension from RTFM (Read The Fucking Manual), is sometimes given in response to a question when the person being asked believes that the question is easily to find in manual or on the web usually using search engine (in this term using Google). This term is a little bit sarcasm (almost).
Beside “Google is your friend” there is also the other version that mostly used, “Let me Google that for you” (LMGTFY). And both are the same. Since the rise of the Web, and ubiquitous search, a similar type of response has involved the idea that by asking questions that could easily be answered by even the most cursory, obvious search, the user embarrasses himself by showing that the very idea of searching before asking didn’t even occur to him. And this the person who answer the question mostly give a link to a website that will animated how to search in Google and got the answer. The answerer think that people is too lazy to find it, and rather ask it in forums. I often saw this kind of answer in StackOverflow, since some of them ask the dumb questions.
Most websites that widely use to animate the Google search are:
1. Let Me Google That For You
This is for all those people who find it more convenient to bother you with their question rather than google it for themselves.
2. Google Is Your Friend
Someone thinks you are an idiot because you were too stupid to check Google before asking a question. They gave you a link to this site as a joke. The fact that you followed it pretty much proves the point.
You can try this link if you want to see how it is works.
