It's simple really. Look across the table at their ship with an expression of total and complete disgust and say "Oh... you're flying JMKs." Then mutter under your breath (but loud enough for them to hear) "Wow, another flying toilet seat list..."
Then groan audibly whenever it does something you hate, like revealing a white sloop or shooting a torpedo, or anything other than spontaneously exploding.
After your inevitable loss tell your opponent "Nice list" dripping with sarcasm. And then loudly say to a bystander or the room in general "Anyone can win playing those flying toilet seats."
