According to Wiki:
Noa is both a male and female first name as well as a surname.
In
Israel, the name
Noa (
Hebrew: נֹועָה) is a popular name for girls. In the
Hebrew Bible, Noa was one of the Five
Daughters of Zelophehad. Noa in some languages are the another form of Noah
[1]
So it's nothing strange or dumbass about the name, whoever think it's dumbass is a dumbass, IMHO.
