n. slang term for a woman's breasts. This has been derived from the term "mammary" which is a gland in the mamalian breast that secretes the hormone prolactin as well as breast milk. The mammaries become especially active during menses and pregnancy as well as while taking atypical antipsychotic medications (Risperdal, Clozaril, Zyprexa, Seroquel) causing what is known as Risperdal Tits.

An example of using it in a sentence would be, Mark: hey did you finish your test? Matt: mams bro of course I did.
