Snake in the Grass?

Several years ago, this guy I used to know named Joe called me a "snake in the grass". At the time, I didn't actually know the meaning of it. I knew a guy named Bobby S. that took great pride in being called a "snake in the grass" and thought maybe I'm one also. This expression has came up again when discussing "class" or lack of it and it made me think of someone that has forced themselves into my so-called life. Yep, it's official!!! I know more than one "snake in the grass" and am thinking about getting me a mongoose... j/k I do not consider myself to be a deceitful or treacherous person but I have been know to cause harm to others. The reason Joe called me a "snake in the grass" was because I was telling him the tale of the low-life piece of white trash that I had to club in the head with my cell phone for fear of my life...there was actually two of them and I hit the big one first. Anyway, if this is what makes a person a "snake in the grass", then so be it. ~Woo Hoo~

Noun 1. snake in the grass - a deceitful or treacherous person
snake bad person - a person who does harm to others
Am I treacherous? (likely to betray trust or marked by hidden danger)
Now is the time for the poll again. Ok, my friends. Do you consider me to be a "snake in the grass"? Be honest...
