What does Altman mean by shrimp and plastic bags?

Altman is an expression pack with shrimp and plastic bags, which means spoof. The expression pack is made by netizens, with the purpose of spoofing and being funny. So it doesn't mean anything, just to make everyone happy. Altman is a tall and powerful hero image in children's minds, which will produce great contrast after being spoofed by netizens. Very interesting.
