look up any word, like bukkake:
Diminishing Hangover Icon. Setting on certain forum websites to indicate that the poster has been out on the lash the night before, and may be slightly hungover. More sophisticated examples include the option to specify what has been drunk, and in what quantities, to allow an algorithm to graphically display the decreasing effects of the hangover throughout the day.
Unfortunately it is impossible to give an example of a DHI on here. I haven't drunk enough, either.
