Is it vegan when i keep the goldfish in my stomach and drop some pellets in there for the fish? Will my stomach juices potentially absorb some non-vegan kibble?
To really understand the shittiness of this post, you need a bit of context. Many East Asian languages rely heavily on onomatopoeias to imply actions and verbs. Gulu gulu (also often written guru guru) is the onomatopeia that represents a tumbling sound, like something being tossed around in a rotating container. Essentially, it implies the verb, "churning." The post is basically saying that it will make your stomach churn and give you a stomachache.
Or maybe - don't swallow whole live fish to start with. Seems like this should be in the book of common sense somewhere. On the other hand, some people eat live octopus and then get smothered when it comes up their throats and blocks their windpipes.
