aye carumbus
something you'd probably (or won't) apply when you hear or see something said or done that's so phenomenal, that you feel like you're stepping into either uncharted territory or another county or on a planet with either an individual or a group of indigenous individuals that significantly differ from your cultural & socioeconomical standards, and when they sound or look so absurd in nature, that the acts or opinions would otherwise be deemed extraordinary, & that they haven't really been physically witnessed or heard by an outsider (yourself or a buddy) since around 1492
