look up any word, like dirty sanchez:
 
1.
Accidorpus are events in time when something happens that is both on accident, and on purpose, but not "Accidentally-on-purpose". The distinction is when something actually being on purpose would undermine the accidentally part, that then would be accidorpus.

An accidorpus event is measured as being 15 Bernard units. Because there are parallel continuities where the event could either be just on purpose, just on accident, or just "accidentally-on purpose".
Laughing at a joke, that you decided NOT to laugh at, would be accidorpus. Because purposely laughing at the joke would be not really laughing at all.
