A riff on the archaic definition of sketch:

1. A hasty or undetailed drawing or painting often made as a preliminary study.

An outline, where not all of the elements are completely clear or known; can refer to a person, place, object or experience; frequently refers to a shady element, something hidden and potentially dangerous; often refers to being up too long on speed and the loss of clarity that comes with sleep deprivation
