Is a reference normally made my rat like creatures (some variations are pigeon or ratty). it is used during a drunken text to refer to two separate parties, normally of the opposite sexy, and is continued by asking if these parties would be interested in making a stew with the person in question. In simpler terms it is a way of referring to two people as beans and the other gravy, and continues by asking if both beans and gravy would like to have a threesome (aka stew!) with the person texting.
the best moment of my life way meeting gravy (katie cuz it rhymes with gravy). then i met satch aka saskwatch or beans for short, aka i want to lick your bean. never before has a single being ever dreamt of mixing beans and gravy. i like both beans and gravy separate. Never had them together but if u fancy a fuckin beans and gravy stew with me, id def be up for it.
