Hope this helps:

 >> V = "aeiou".freeze
=> "aeiou"
 >> C = ("a".."z").to_a.join.gsub(/[#{V}]/, "").freeze
=> "bcdfghjklmnpqrstvwxyz"
 >> DBL_SYL = /([#{C}][#{V}])\1/.freeze
=> /([bcdfghjklmnpqrstvwxyz][aeiou])\1/
 >> %w{waikiki dodo paparazzi}.each do |test|
?>   puts "#{test} => #{$&}" if test =~ DBL_SYL
 >> end
waikiki => kiki
dodo => dodo
paparazzi => papa
=> ["waikiki", "dodo", "paparazzi"]
