when an adult is throwing a full on tantrum, screaming, slamming things, possibly crying; akin to a tantrum expected from an infant or toddler (a tantrum in which said infant or toddler was eating a fudgesicle just prior to becoming upset, so they drool and sneeze mucous mixed with the melted fudgesicle, thus fudgesicle juice.
The woman's grocery cart barely tapped the door of his Mercedes, and the guy went nutzo... screaming, and crying so hard I thought he was gonna start sneezing fudgesicle juice.

also used preemptively...
Hey, calm down now before you start cryin' so hard you're sneezing fudgesicle juice.
