In zero correlations, there is either a) no meaningful relationship between the two variables (the association is a random one) or b) the relationship is other than linear (i.e., a curvilinear relationship).
An example of a zero correlation with no meaningful relationship is... the more you masturbate the more kittens die of unexplained deaths.
An example of a zero correlation with a curvilinear relationship - the taller a stripper is, the more she weighs.

A correlation coefficient of zero means that two things are not correlated to each other.
A coefficient of zero means there is no correlation between two variables. A coefficient of -1 indicates strong negative correlation, while +1 suggests strong positive correlation.
