It certainly happens when you are extremely alcohol dependant. It's in line with the beginning of organ failure, so its usually accompanied by internal bleeding. That means that there's blood in your puke and in your stool at the same time. It makes for some wonderful and exciting colour combinations.
Infact I personally have spent many nights kneeling and puking in front of the toilet and at the same time, spraying bloody diarrhoea all down the door behind me.
Likewise I often switch it up and just sit back on the toilet, relax and vomit all down my front. It's actually quite a kinda sexy feeling as it covers my cock and balls and drips into the toilet.
Truthfully though, the above examples don't very happen that often these days, as I am unable to get out of the bed without assistance, so I just turn on my side and let things 'Spray where they may'...
Good Times
