A term to refer to anything, usually from the 1970s that is stale, dingy, dilapidated, and often came in horrible shades of yellow or brown (The actual colours of Urine and Faeces), imitation wood and plastic and came in the forms of hexagon-ish shapes. This term is named after the Grundy TV logo seen in the opening credits of Sons and Daughters for obvious reasons.
