Mother's Day lunch - "Thon's a clooster!"

(NB: If you're reading this on Facebook, the original post is from my blog). My parents came off with this on Sunday, and I don't remember ever hearing it before.

Chambers Concise Scots Dictionary has it as:
• clooster n a mass of something wet or sticky, mud etc 19-, chf Galloway

James Fenton's The Hamely Tongue - a Personal Record of Ulster-Scots in County Antrim has it as:
• clouter [cf.Sc. cloiter a disgusting wet mess; possibly of Low German origin]

Hilary just hopes they weren't talking about the Sunday lunch she'd made that we were all eating at the time!
