I've been marketing to teens and young adults for a few decades (ouch) and my Urban Dictionary game is pretty tight, but this one was new to me: on fleek (adj): very good; on point

But wait, you ask, how do I use it in a sentence? Well, this charming young lady has volunteered to demonstrate:

Translation: I'm headed out to a club or party, where I plan to enjoy cocktails, dancing and laughter with friends. I'm particularly excited my eyebrow grooming turned out so well because when you look good, you feel great!"

Now you try!
