1. An uncharacteristically large, lumpy, or otherwise misshapen rear-end that is attached to an attractive woman.
2. Also considered to be the "sound" the woman's jiggling, dumpy butt makes as her too-small legs carry it around: "(woman walking) clunk-k-clunk-k-clunk."
1. "I was at the bar and this chick was giving me the 'eye.' She was pretty cute, so I shot her a smile. My hopes here dashed, however, when she walked by to use the bathroom. What had appeared to be a thin, in-shape, young vixen turned out to be a girlie carrying a little 'extra baggage' -- she had a clunkle."
3. "Damnit. Clunkle."
