A mildly racist slur for cardassians. The term 'cardie' is MUCH stronger. Please do not utter either in front of a cardassian unless you are an EXTREMELY skilled fighter.
The term 'spoonhead' is basically equivalent to whatever mild insult for races you care to mention.
Spoonmeat is a luxury food item, usually available from frozen food supermarkets in the United Kingdom such as the popular 'Coldland'. It is traditionally served with an accompaniment of 'Carbonated Dipping Jam' and is popular on special occasions such as 54th birthday party's.
"My, this Spoonmeat is delicious! And tell me; what is in this Carbonated DippingJam?"
