A feature of many web browsers that allows the user to prevent any data (like history, cookies, or the cache) from being stored while it is on. Also known as porn mode for really obvious reasons, but may be used whenever any sensitive/confidential information is going to be transmitted.

Private browsing is more comprehensive than simply erasing the history, because that's just a list of URLs, and browsers also save things like cookies (for sites to remember you) and images in the cache (to load faster later).

Private browsing is just a browser feature — there are other ways visited sites are tracked (for example, by your Internet provider), so it's not foolproof.
Say you are about to purchase a surprise for someone. If you choose a private browsing session, after you're done, other people won't see what gift you bought, or your credit card number, or your drug trafficking, or your porn.
