"Lem" can be used as both a noun or a verb, and is basically used to describe a copycat, or indeed the act of copying. Mostly used in the derogatory sense, it can be used to describe a rip-off, a fake, or even an unintentional coincidence.

The word was coined in the early nineties, and is based on the computer game Lemmings, in which mindless rodents follow each other to their grisly deaths.
