Tempera tantrum

[Julene]

Refers to a noisy/[voluminous] outburst of frazzled-nerved emotion involving watercolors, either emanating from a creator/observer of a messy spill/soiling involving said paint, or the resulting preposterous canvas-creation (think, [abstract art]) when the genius [painter] supposedly experiences a creative epiphany and totally goes wild with his colors in an effort to supposedly illustrate his inspirations, emotions, Heavenly-based vision, etc.
