[We are not entirely use of the references in this cartoon. In Thai, to call someone a “catfish face” is an insult meaning they are very ugly.
Here, the cartoonist seems to compare pro-Thaksin Red Shirts with catfish. So when PM Prayuth speaks there is an endless amount of ridicule towards his statements–mainly from those who oppose the coup.
However, when Yingluck was PM, her frequent gaffs and the obvious signs she did not really run the government were widely ridiculed. However, pro-Thaksin Red Shirts still firmly lauded her actions and insisted she was a very capable prime minister.]
