I'll give it a go...
Crosstalk is when some of the left-side of a stereo-channel leaks into the right-side and vice-versa. For example, I have a stereo EQ with a relatively high level of crosstalk, when I send a signal to the left channel I can measure a small amount of signal on the right-channel output. It varies widely between devices and can be as high as -40/50dB, but is normally <-80dB.
Normally - this is unwanted, it decreases the amount of separation between your channels and can make your mix sound narrower, BUT - that can be perceived as an increase in tightness, or glue. Also, as Bob pointed out, the crosstalk might be out-of phase with the signal. In this case this would actually increase the difference between the two channels and make your mix sound wider. It might also happen more at certain frequencies than others, I seem to remember that inductor-based EQs suffer particularly from crosstalk at high-frequencies. In any case it's an integral part of the sound of a stereo analog-device, which makes it strange that Waves didn't model it.
