Something that is random, not based on skill. People think this refers to an asshole (where your crap shoots out), but it's actually a reference to the dice-rolling game called Craps.
A crap shoot is a view of the future, seeing it as variable and dynamic, and totally unforeseeable. Besides the fact that it is slightly more black than the present.
Inserting your fingers into a vagina and wildly shaking them from side to side and up and down until she gushes, then taking your poon soaked hand and slinging it on her face.
Jeff finally got to finger his girlfriend but she squirted all over his mom's sofa...so he gave that little whore a crap shoot.
