The word Ribs comes from an old (now not used !!) Welsh language meaning "small ferocious reptile with bad breath !".

The most distinguished charateristics of the reptile is its mating dance, this was usually preformed on a bar in various clubs and bars, and involved the shaking of it bare arse to any protenial partners. Brightly coloured under garments were sometimed used to out-do other reptiles also trying to attract mates.
The ribs is a small fair but rough skinned reptile now only found in southern Spain
