How Much of Today's Slang do you Understand?

I like to think my vocabulary consists of a healthy mix of the slang from my youth and today. However, I'd be lying if I said I knew what all of it meant. I don't think I could carry on a conversation with some of the "youngns" around here. I think my favorite time for slang was the 90's, my vocab game was all that and a bag of chips guys! Here's some of the lingo from back in the day and then some from today do you're language skills can be on fleek! (Pretty sure that means good) Are you guilty of using any of these?

Ok, those I figured you'd know but what about the slang the kids are using today? I included definitions so we could all be in the know.
