wiki say xuete is a kind of ppl who eat pork.
Other authors consider that it may derive from the word xulla
(pronounced xuia or xua, which means a type of salted bacon and, by
extension, pork) and, according to popular belief, makes reference
to Xuetes being seen to eat pork to
demonstrate their disaffection from Judaism, but it seems
more reasonable to link this etymology with the tendency, present
in various cultures, of using offensive names related to pork to
designate Jews and Jewish converts (see, for example Marrano).
