Originally a typo to the more common DIACF (Die in a car fire). This expression can be used alternatively. Because of it's more painful mental image, it makes it a much better acronym to use when wishing harm upon another.
Means that if you don't do it, you will regret for the rest of your life! So DIADRI! Do it and don't regret it!
Me: ''I would so try that out, but got no time!''
Him: ''Promise you, you won't regreit it! If you don't make that bungee jump you would regreit it for life!''
Me: ''But got no time.. well.. DIADRI!! ''
