Lime In Me Eye/Lime In Yer Eye
Last week, Christine Zimmermann left this comment on Beavish Archive.
"Lord Beavish. We have a contribution to Beavishism. We've worked out the 'phrase' but can't work out quite what to have it mean/ circumstance in which to use it. "Lime in yer eye" (alternative "Lime in me eye")."
I suggest that because having lime in your eye could be quite painful - either lime juice or just lime - then this could mean that the person is in pain in general.
