Fishy business意思

"Fishy business" is an English idiom that means something suspicious or questionable is happening, often referring to a situation where there is deception or dishonesty involved. The word "fishy" means strange, suspicious, or hinting at something being amiss, and "business" refers to any kind of activity or dealings.

For example, if you suspect that your coworker is stealing money from the company, you might say, "There's something fishy going on with the accounting department." This implies that the situation seems suspicious and possibly dishonest.

The origin of "fishy" in this context is not clear, but it may be related to the idea that fish have a strong smell, and something that smells fishy is not pleasant or trustworthy.
