Threshold Frequency is the maximum frequency by using which electron can be ejected from a particular metal. The maximum kinetic energy of an electron ejected using the light of threshold frequency is zero. Which means the out of all the electrons ejected using the light of threshold frequency the one with the highest KE is zero and all with KE lower than that (negative) will go back into the metal.
This explanation was according to my understanding of photoelectric effect.
