When a man does anal with a girl and makes her bleed analy on his dick, then puts his blood-covered dick in her mouth. Then he cums in her mouth, mixing the white cum with the red blood, turning it pink. The girl now has a bubblegum looking substance in her mouth, she then proceeds to blow a cum bubble with the "bubblegum", therefore completing the the bubblegum effect.

Someone people turn to when they're sad who makes them feel better.
