Daft question

Why are much wanted/lusted over polishes known as "lemmings" ? Anyone know ?

I've wondered that too, I think it's silly   

When I was young we used to say we really 'lemmed' something if we wanted it. Don't know if its from something like that.

From Urban Dictionary:

"A lemming refers to a purchase/wished-for-item which results from reading an enthusiastic post about a new fabulous product. Overcome by compulsion, readers follow like lemmings diving off a cliff.

Originally coined in the alt.fashion newsgroup in the late 90s, the term has permeated numerous beauty boards/forums/sites.

May be used as a noun or verb. May apply to the buyer but more commonly to the item of desire.

A flemming is a fledgeling lemming."

I'm not sure how accurate it is.
