I like it small and simple:

#!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper;

my %hash;
my @array;

while (<DATA>) { chomp; push @array, split "- " };

%hash = @array;
print Dumper(\%hash);


__DATA__
ABD - some text
ACDB- some more text
WD  - more text
    - which spills onto the next line
SD  - another line
