The puddle of ass sweat left on a seating surface after an intense workout, spicy food, or when the climate is too humid.
OMG - On my way home from the gym, I stopped at the pharmacy to pick up a prescription. I took a seat while on line, and when I got up, I had left a huge cruddle. I didn't know it was there, but some big heffa got all up in my grill, and shouted "What's That??" I was like "it's a cruddle, Heffa".
