The plural form of "couch", which is defined as anything included in the same family of furniture as sofa, loveseat, but excluding chair-and-a-half. This alternative spelling of the plural form is a direct result of the increasing use of the "i" suffix to many words in elite engineering institutes and universities in classes. The more couchi, the better.
That house has 4 couchi facing the big screen tv. It's so dank!!!
