Glasgow Patter: daily life...
clatty or clarty
This means dirtied with mud or just plain dirty: "Don't you dare tramp ma good carpet wi they clatty boots on." "Ye should see the state a his hair: pure clatty-lookin."
A clat is a term used for a person considered dirty: "The wee clat picked a sweetie up aff the grun an et it."
