When it comes to sweating, the phrase "pit out" is commonly used to describe excessive perspiration that occurs under the arms. However, there are numerous synonyms that can be used to convey the same idea, such as "sweating buckets", "dripping with sweat", "drenched in sweat", "soaked with perspiration", "sweating profusely", or "sweating a river". Additionally, "pit stains" can be used to describe the unsightly yellow marks that are often left behind on clothing by excessive underarm sweating. While there are many terms to choose from, they all convey the same general idea of excessive sweating that can be uncomfortable and embarrassing.
