A gurdlay is somebody who goes around dark alleys offering to finger your anus for money, normally for fees of approximately $2, but he will do it for free if you lick his fingers afterwards. The term "Gurdlay" comes from the gurdlays going around to their targets saying 'Good day' to them but due to speech impediments caused by extreme incest, it sounds like 'gurdlay'. DO NOT approach a gurdlay.
Person 1: A gurdlay came up to me behind Taco Bell last night!
Person 2: No way! Did you lick his fingers?
