Internet meme 'My knife and shield'

1. Origin: Originating from a rapid, slurred phonetic transcription (mishearing) of the English phrase What the dog doing? (What is this dog doing?). Due to its vague pronunciation and fast speech, it sounds particularly like the Chinese '我的刀盾' (my knife and shield). It initially appeared in funny pet videos on international websites, and later went viral after domestic netizens created derivative works, pairing it with the catchy Cheems / marmot image (a composite image holding a knife and shield).
