our safeword became an inside joke and i love it

so years ago we picked "pineapple" as our safeword bc it sounded ridiculous and we'd never accidentally say it mid... anyway. now it's become this whole thing where any time pineapple comes up in normal life we both crack up. saw it on a pizza menu in dublin last yr and she nearly spat her wine out. asked the waiter for extra pineapple just to mess w me at a friends bbq last summer. anyone else got a safeword that became more inside joke than actual safety net? still works when we need it but mostly its just... us
