Gee wiz, gee, jeeze, geeze are all, in root form, a euphemism for Jesus. That being said I personally do not look at them the same way as GD or Jesus or Jesus Christ used in that way. My language is bad I will be the first to admit that but I really never use GD or the others. It makes my skin crawl to hear it actually. But I for sure am not gonna start calling out people who say gee wiz lol.
