The slang term "gummer" has several synonyms, including " gum job," "palming," and "teeth job." All three of these terms refer to oral sex performed on a man without the use of teeth. Some people also use the term "blowjob" as a synonym for "gummer," although the former generally refers to oral sex with the use of teeth. Other slang terms for oral sex include "head," "blowie," "BJ," and "fellatio." While these terms are often used colloquially, it is important to remember that sexual acts should always be consensual and safe. Communication and mutual respect are key components of any healthy sexual encounter.
