Pop Noise is the low frequency current fluctuation in semiconductors. I remember that the naming has its origin in the acoustical noise of a popcorn machine.
The 1/f semiconductor noise played on a speaker have great similarities with the popcorn machine. The current fluctuation is by abrupt changing the semiconductor current by trapping and releasing electrons. That is a discontinuous effect and depending on the amount of charge responsible for current flow control in MOS for instance you can see the bursts on scope. Some report at 45nm single digit % current changes!
There are further microphone pop noise from the abrupt breath. The other supply pop noise is called click noise.

There is an article describing time domain 1/f noise modelling:
Time_domain Modeling of Low-frequency Noise in Deep-Submicrometer MOSFET
n.H.Hamid, A.f:Murray, and S. Roy
IEEE Transaction on Circuit and Systems I:Regular Papers
