Means "mother" in Ireland, typically used in Cork slang.
"C'mere to me lad, I saw your 'ol laid last night and she was savage."

"How's your 'ol laid? I heard she's up the walls with work!"

"My 'ol laid got laid last night, he laid it into her while she layed!"

"The 'ol laid got the dole today, she'll be on the jar tonight I'd say!"
