And how is calling me ****-Salsa NOT pointing it out?
Largely because until you clarified it, I had no idea what was behind those four asterisk. Given the lack of gentlemanly behavior of some posters around women, I had assumed they were attacking your femininity.
Sulsa pronounced with the schwa sound for the "u" would be diarrhea. Sool-Sa would be "technician." Mkay?
설사/Seolsa is indeed the pronounciation of diarrhea. Where as 術師/술사/sulsa is the term you're looking for. The problem is that it is a term that has virtually no use outside of the Hwarangdo's imagined past, and the average Korean is going to think a Westerner is misprouncing a term indicating that they have stomach condition. The last time I saw it happen, that person was directed to the restroom.
The only area that the term finds much use is in manhwa, Korean comic books.
