windae licker 

A Scottish colloquialism (used mainly in the West of Scotland) used to define someone of limited mental ability. This term seems to have superceded the colloquial term, mongol.

He/she eats lots of cocopops, so I think they're a windae licker.

windie licker 

Originally a Northern Irish term, but spreading rapidly through Usenet. A derogatory term for someone of very low intelligence or who is mentally retarded. Originates from the buses that transport mentally deficient people where the occupants can be seen licking the windows.

M3 licensees are all a bunch of windie lickers
