To put someone on the mushroom list is to keep them uninformed and to feed them rubbish answers. It comes from the best conditions in which mushrooms flourish "You keep them in the dark and feed them sh.t".

Get the mushroom listmug. The alias of Tiffany, a member of the Korean girl group, SNSD (Girls' Generation). Notoriously known for mispronouncing her nickname, "Brighter than Jewels" Tiffany, as "Brighter than Mushrooms" Tiffany; hence the nickname "Mushroom Fany." This has caught on with the SNSD fandom and has been adored by fans alike.

Get the Making a Mushroommug. A situation where a man has sexual intercourse with a pregnant woman, who at some point miscarries her child on the penis of the man.
