A Holistic Steamroller is something that crushes your mind, body and spirit. It is an occurrence or person that is so devastating to one part of oneself that it crushes the others also.
For example, a physical accident or illness can be so destructive that it tears down the mind and spirit, too. Or mental abuse can lead to a physical and spiritual demise, as well. Likewise, some terrible atrocity that cuts down the spirit will also afflict the body and mind, crippling the emotional life and causing physical illness.
Example one:
Caring person: hey how are you?
Sad lady: I'm fine. No, not really. I've been hit repeatedly by a holistic steamroller and I don't see the point anymore. I'm in physical pain, my man cares more about gadgets, fantasy women and food than he cares for me, and my friends just want what they can get from me. I feel used and neglected at the same time.
Example two:
Caring person: hey How are you? I heard you were in the hospital...
Afflicted Man: (mocking) yeah, I'm great!! I can't work, had a seizure, found out I have a cancerous brain tumor, my wife is a drunk, we have three babies to feed, and nobody gives, or ever has given, a shit! Howdya think I am???!!!
Caring person: (to self) that's a holistic steamroll if ever I saw one...
