How do I use BTC?

I don't know if this is the right section or not, but I've never really learned how to use bitcoin. How do I get bitcoins? How do I pay with them? I just never learned and sorry for sounding like such a noob. Well I am new to OG usernames but I never used bitcoin before.

Sign up at https://blockchain.info

Buy BTC from seller

profit???

sign up at blockchain.info as stated above, and either buy them from a seller (for ridiculous rates, and since you're new no one will sell to u) or buy from coinbase.com for less than 5% (must have a bank acc)
