The feeling of not remembering certain parts of the previous night, similar to a slide machine missing slides in a slide show. Usually caused by excessive consumption of alcohol.
An example of a Slide Missing:
Frank: Hey man, what happened last night after Sally poured beer all over John?
Jack: No idea man. There are a few slides missing from last night.
