I think that this one is likely to be very regionally dependent. 
Such things fascinate me.  So I'll play ...

or, 'formal parameters'.  But they aren't arguments.

yes, but I also call them 'actual parameters', almost exclusively
when I want to contrast them with the 'formal parameters', or 'default
parameters' in the definition.

Laura Creighton  ... who wouldn't be surprised to see somebody who does
                 it precisely the other way around ....
