Etymologically, weak
sauce was born in Long Beach California circa 1996. It was inspired by the G Love song "My baby got
sauce" to which the adjective weak was added and a neologism was born. I used the term intermittently and was surprised when, two years later, I was visiting northern california and heard it used. Since then, it has spread and false claims as to it'
s origen have been made.
The full usage is now commonly considered passé. Currently, in Long Beach,
sauce is an acceptable description of something thats shitty. It is interesting that G
Love's "sauce" was a good thing and it has in fact become a polar term.
