Using two specific models and a model-independent formalism, we show that in addition to the usual quadratic ``side,`` ``out,`` and ``longitudinal`` terms, a previously neglected ``out-longitudinal`` cross term arises naturally in the exponent of the two-particle correlator. Since its effects can be easily observed, such a term should be included in any experimental fits to correlation data. We also suggest a method of organizing correlation data using rapidity rather than longitudinal momentum differences, since in the former every relevant quantity is longitudinally boost invariant.
