Language

Using youthful language, like scrilla for money and kicks for sneakers, makes you really popular with the younger crowd.  Studying urbandictionary.com ensures you won't get ripped off when trying to buy street goods in Hollywood and your kids will definitely feel comfortable talking to you about sex.

Acronyms also keep you in the loop, so LOL, LMAO and BRB to your heart's content, especially if you're a MILF.
