Poing is a gabber track by the Rotterdam Termination Source released by Rotterdam Records in 1992. The song, composed by Maurice Steenbergen and Danny Scholte, featured a minimalist approach: during the whole length of the track a distinctive pounding beat with a "poing" sound can be heard. The track topped the charts in the Netherlands and Denmark. It reached number 27 in the UK chart in November 1992.
The English football team West Bromwich Albion F.C.'s "Boing Boing" crowd chant, is reportedly based on this track.
