“洗衣液” means “laundry detergent,” and “男孩” means “boys.” This term, coined by Chinese netizens, refers to “neat and tidy young men,” who may actually smell a little bit of the detergent because their clothes are always fresh from washing. Such a person may also trim their fingernails often and keep their teeth clean and white. Handsome or not, this type of young men are popular among women.
