When your whole world caves in on top of you (
metaphorically or physically), you can be described as being crushed.
You can be crushed by large weights, but the most painful type of 'crushing' for a man is when he is smitten with a young lady over a long period of time (a co-worker or flatmate for example), only to be rejected when he attempts to initate a
relationship. Normally a man crushed in such a way will be inconsolable for a few weeks, and will probably never recover. The only way for a man to avoid being crushed in such a way is to avoid ever getting
emotionally close to a woman, and as such lead a lonely but un-crushable existance.
Women, being the apostles of Satan, are not crushable in this way. But they are crushable physically.
