Don't know about a layman's definition, but here is one from a glossary of geophysical terms for tau (time constant).

time constant: The time required for an electromagnetic field to decay to a value of 1/e of the original value. In time-domain electromagnetic data, the time constant is proportional to the size and conductance of a tabular conductive body. Also called the decay constant.

I'm not a geophysicist, but interpret this to mean that the higher the tau or time constant, the larger and more conductive the body.
