We study the transverse-momentum imbalance (acoplanarity) of a gluon jet propagating in an expanding quark-gluon plasma. Under reasonable assumptions for the gluon cross section for interaction with a quark-gluon plasma, and with a hadron gas, and a proper space-time picture of the time evolution of matter produced in nuclear collisions, a simple formula is established relating the acoplanarity distribution to the jet emission angle, the total multiplicity of produced particles, and the nuclear radius. We find that for reasonable values of the jet-plasma cross section, the acoplanarity distribution stands out significantly beyond experimental cuts.
