THE REAL DEFINITION:
East Bay (Fremont/Hayward originally), early-mid 1980's. Original slang was "hecka" (a bastardization of the GREEK prefix "heka", meaning 100, or more generally, a large nonspecified quantity). So it originally had nothing to do with profanity/cursing. However, it was soon upgraded to "hella" by those who thought that it was somehow related to the word "heck".
My definition is hella sweet.
