of who gila?

I was asking Granduncle for Disembarkation/Embarkation cards. He travels across the causeway frequently and has stacks of the cards stashed in his cupboard.

He went into the room and came out holding 20 of them. Sorry didn't tell you in the first place, but I only wanted 8.

I showed the thick stack of cards I was holding to LancerLady. "Gila!", she said.

"Who gila? Who gila?", Lancerlad interrupted.
