It's called Buddhism, and you should probably learn a lot more about it first. It's kind of insulting to people who take their religion seriously, when people pop in and out like it were some sort of trend.
Most major cities will have a Buddhist community. If you are curious about it, it is better to ask them "I've heard of Buddhism, but don't know much about it, and am curious. What can you tell me?" There are different schools of Buddhist thought, just like any other major religion, just so you know ahead of time.
