I looked up plasticine, and the first 2 sites I found quite bemused me. Warning: the first is a commercial site, but I'm putting the link in case anyone wants to verify my quote. Plasticine is one of the most popular names in modelling clays toady.

The other has this: This site is about plasticine (plastiline).May be it's not the art. It's rather expression of momentary mood. Puging plasticine you put part of yourself to plasticine lump. And you feel that your mood is changed... Puging? Then at the top, I read We hope you will try to pug plasticine some day : )
