Here are some examples of how "fishy" is used:
* "Her story about being stuck in traffic for hours seemed fishy. I think she was just late." This implies that the person's excuse is suspicious.
* "There's something fishy about that deal. The price seems too good to be true." This suggests that there's a potential catch or hidden problem.
* "The politician's sudden change of heart on the issue is fishy. I suspect he's got something to gain." This implies that the politician's actions are motivated by something other than genuine belief.
The term "fishy" originates from the idea that fish have a strong, sometimes unpleasant smell, which can be associated with decay or decay. This association makes "fishy" a good way to describe something that feels "off" or "rotten" in a figurative sense.
