What is Backstab?
1.
To betray a friend by doing something "behind their back" that would harm them in any way.
Joe backstabed me when he told Tori about our secret last weekend.
2.
So called "friends" will act like they really like you, be friendly with you. And then goes out and make up lies to your girlfriend that you're seeing someone else and that he has been covering for you for the whole time. This makes your girlfriend seem confused and think you do not take your relationship seriously.
When we found out what that backstabbing prick did, we encircled him and beat the living sense out of him. Now he cannot talk and cause any harm to anyone.

3.
Pretending to stick up for you at work and later you find out they've been talking trash about you. (In fact, saying the exact opposite). Striking you down from behind.
Jon told me that he stuck up for me. But he actually voted to get me fired and he knew in advance it was going to happen. He backstabs.
