The line comes from the Welcome Home Restoration Project, a web project built around a fictional lost puppet show and its recovered media. It appears in A Darling Broadcast, a radio-style piece presented as restored material on the project site. The invented word thankulations mixes thanks with salutations, matching the show's polite, old-fashioned presentation. As clips from the project circulated among fans online, this short greeting became a standalone reaction sound, reused out of context for welcomes, invitations, and ironic thank-you moments in edits and streams.
