We study three-body nonleptonic decays B{yields}VVP by introducing two-meson distribution amplitudes for the vector-pseudoscalar pair, such that the analysis is simplified into the one for two-body decays. The twist-2 and twist-3 {phi}K two-meson distribution amplitudes, associated with longitudinally and transversely polarized {phi} mesons, are constrained by the experimental data of the {tau}{yields}{phi}K{nu} and B{yields}{phi}K{gamma} branching ratios. We then predict the B{yields}{phi}K{gamma} and B{yields}{phi}{phi}K decay spectra in the {phi}K invariant mass. Since the resonant contribution in the {phi}K channel is negligible, the above decay spectra provide a clean test for the application of two-meson distribution amplitudes to three-body B meson decays.
