LFO stands for Low-frequency oscillation. The name comes from the fact that it is an electronic signal with a low frequency, which oscillates to create a rhythmic pulse, or wobble. LFO's are common in synths and help vary their sound capabilities.
A number of popular effects are based around low frequency oscillation, namely chorus, vibrato, phasing, flanging and rotary speaker effects.
