Since you told me about "Beards" I've been hearing it everywhere. I heard people use it on Howard Stern a bunch of times and it was on some TV show somewhere. At least four or five times I noticed it since you told me what it was.
It makes me wonder how many times I've heard it in the past and thought they were talking about the hair on men's faces. I had never heard that before and now I'm hearing it all the time.
It's like when you learn a new vocabulary word and all of a sudden it pops up in your everyday encounters. Like I learned "bete noire" and I've seen it at least three times in the last month. Look it up if you don't know the deffy but maybe you've known all along. I wonder what other slangs you know that I've never heard of?
