A butchered misuse and gross misunderstanding of the phrase 'wreak havoc', perpetuated by uneducated communities in the rural United States. Typically these individuals do not understand the meaning of the word 'wreak', so their simple minds believe 'wreck' is an acceptable substitute due to its thematic similarities to the word 'havoc'.
The correct phrase, 'wreak havoc', means to bring about destruction and chaos.
This is in contrast to the words 'wreck havoc', which would literally mean to destroy destruction.
Example: Through the perpetuation of my ignorance, I shall wreck havoc upon the english language.
