kerbside quiche
A combination of excessive alcohol and fast food you had eaten & drank not that long ago and then vomited up in a nearby gutter, doorway, footpath etc. When it is vomited up its all mixed together thus you now have a kerbside quiche.
Tonight, Alfred had drank so much piss, he had even eaten a whole pizza to himself. On the trip home he felt sick so we had to pull over and let poor old Alfred do a kerbside quiche.
