Why do we use the word Crush to express our attraction and feelings of attraction towards someone? Why the word Crush?....

I was walking in the city one day and saw this written on a wall.

The definition of crush is to be hurt.

It's a word filled with so much negativity. So, does that actually imply that all your "crushes" will hurt you, destroy you, damage you?

That's absurd. Someone should seriously take this into consideration; change the term...please?

I need to add a " HAHA ". I'm no depressed okay. haha..I just like to know why..
