A vibrant sticker design featuring a speech bubble with rounded corners and a thick white outline, filled with a deep black field speckled with tiny white stars resembling a night sky. Radiating outward from the center are bold, colorful rainbow stripes-red, orange, yellow, green, blue, indigo, and violet-creating a dynamic burst effect. The text "EXISTENTIAL" is stacked above "CRISIS CLUB" in clean, sans-serif, all-caps bright white font, centered over the rainbow burst. Small scattered white stars surround the text, enhancing the cosmic theme. The overall aesthetic is playful and slightly ironic, with a modern graphic design style, digitally created with crisp lines, flat colors, and no texture or shading. The sticker is isolated on a plain white background, isolated with no shadows or reflections, symmetrical and balanced, evoking quirky humor and self-awareness.
