HIP TERMS I DON'T UNDERSTAND

My birthday's in a few weeks, and the farther I get in my 40s, the more slang escapes me. I've tried so hard to keep up and thought I was doing well, but here are some I've missed out on. Anybody else?
  1. Bae
  2. Fleek
  3. 💯
  4. Mommy/Daddy (referring to celebs as such)
