The process of taking part in sexual activities with either a single or multiple jellyfish and then also consuming the jellyfish afterwards. Jelishing usually results in extreme burns and stinging pains in the genital area, as well as inside the mouth from eating the flesh of the jellyfish. It can be extremely dangerous for one to jelish, as many species of jellyfish have stings that can result in death. It is therefore recommended to stick to weaker stinging jellyfish and avoid jelishing with jellyfish such as the Portuguese Man o' War or the box jellyfish.
"James just left hospital after a month of recovery after making the foolish decision to jelish some of the jellyfish down at the beach."
