Crud is that stuff that you find caked on to the back of a household oven. It also is popular with little kids for a substitute fof "crap", so they don't get in trouble and have to go to the office.

a word used instead of "crap" most people say this if they do not curse so instead they use crud which sounds very similar yet some people who curse say crud anyway. crud can mean poop, sludge, slime, or pretty much anything goopy or sludgy.

CRUD: "...an acronym for 'Chalk River Unidentified Deposits.' ...black, highly radioactive substances found on the inside of piping and components at the Chalk River nuclear reactor ... CRUD has now become a standard industry term referring to minute, solid, corrosion products that travel into the reactor core, become highly radioactive, and then flow out of the reactor into other systems in the plant. ... CRUD can settle out in crevices or plate-out on the inside of piping in considerable quantities ... The major components of CRUD are iron, cobalt, chrome, and manganese ... CRUD is a concentrated source of radiation and represents a significant radiological risk because of its insolubility." (United States Federal Energy Regulatory Commission, Testimony of James K. Joosten, September 15, 1997, pg. 13-14)
