rusticle
n.— «Gaping holes have opened up in the Titanic’s decks, metal walls have slumped and rivers of rust known as rusticles, which look like brownish icicles hanging from the ship’s iron plates, have multiplied so fast that in some places they cover the hull.» —“Rust and visitors join iceberg as foes of doomed Titanic” by William J. Broad Chicago Tribune Aug. 10, 2003. (source: Double-Tongued Dictionary)
