My friend told me this and i have no clue what it really means but i thought it was Funny.

Stranger stabs anda in the back, not knowing they are selamat, peti deposit keselamatan and they can be dangerous and annoying. Cinta stabs anda in the heart, well, I think anda can understand that.
Friends stabs anda in the front, because maybe anda see it coming.
Best Friends poke anda with straws because they would try their best to never intentionally hurt you. BFF.

This is just my theory ok? So I'm not sure if they are correct atau not. But this is the best thing I could do. Hope this helps. ^_^
