1. let me google that for you, meaning, "Holy fucking shit. Google that yourself. Don't fucking ask me."
2. Another website which may quite possibly be the best website ever, along with ogogle. You use this website when someone asks you a stupid, stupid, question, that they can find out themselves just by searching on google. When you go to http://www.letmegooglethatforyou.com , you type in the keyword you're searching for, then you click search, then you will get a link below the buttons. Now, give this to whoever asked the dumb stupid question, (and see for yourself too what it does) and wait for his/her reaction.
