Haha... as an interesting note, I was being labelled an arahat
by one of their 'seniors' once.
It should be known that in their community, 'arahats' has two
definitions: in the technical model (where phenomenological
criterias are accessed for diagnosis based partly on Daniel's,
Visudhimagga's, Mahasi map), and the fetter model (the Buddha's
definition of the four paths).
Generally when 'arahat' is being spoken there, it refers to the
technical model. To me (and many others), the technical model
arahat is simply something like stream entry in the fetter
model.
