A term used in the scientific community. When another group is using a scientists results or ideas without his knowledge to publish something before him, this scientists is getting scopped. Scooping is considered a bad behaviour among scientists, close to cheating and admitting that you don't have your own ideas. However it happens on regular basis leading to a high level of paranoia (especially among grad students, where the carreer prospects depend on the number and quality of publications).
XY got scooped (to get scooped). The research group from that other university used the infos from his poster to publish before him.
