look up any word, like swag:
 
1.
The feeling a person can get when he/she realises that she is still holding on to a doobee (joint).

The word "Boganoia" comes from the name "Bogart" which comes from the term "Bogart a joint" which was coined due to the legendary Humphrey Bogart and his cigarette smoking antics
A victim in such circumstance might say something like "Did I just smoke all of it by myself??" whilst guiltily glancing at his compatriado's.

The person suffering from "boganoia" might also be referred to as "boganoid"
