Good question. Here are some common pronunciations:
$_ - "it" or "the topic"
foreach (@line) { chomp $_; }; # for each line, chomp it
$! - "the error code" or "buck bang"
$@ - "the exception" or "buck at" or "the error"
@_ - "the stack" or "at under"
Many vars can be called by their English.pm name.
$_ - "arg" -- I've never heard that
$! - "errno" or "error number"
$@ - "eval error" -- I'm not sure I've ever heard that
$$ - "pid" (or "buck buck")
$? - "child error" (I have never heard "buck hook")
$, - OFS
$\ - ORS
$/ - RS
$< and $> and $( and $) - uid, euid, etc
$0 - "dollar zero"
Lots of the funny ones are rarely used enough, or their pronunciation is short
enough, that you just say them the way you would if you knew nothing about
perl:
@ARGV - "argv"
@INC - "ink"
%INC - "percent ink"
$; - "dollar semicolon'

Nothing would. Perl does not have an office.
