Funny story I didn’t know it was supposed to be pronounced as blohai, until one time I was hooking up with another trans woman from tinder and she got excited when she saw my blahaj and kept pronouncing in the worst way possible (correctly but I didn’t know). I chose to not “correct” her but I was like wow weird
It bugged me so much that I googled it next morning and realized I’m the silly one
Also, the blahaj is called steve in my household and it’s the only way one shall refer to steve.
I think I might be wrong, but I personally say it blah ha. But I don't think this is how its meant to be said lol, like you said blo-hi is the one that I think? maybe is correct
