An orgy with multiple participants where the men defecate onto the women's breasts before titty fucking them while all singing 'Shitty titty gang bang we love you' in homage to the show 'Chitty Chitty Bang Bang'
A sexual move when a male inserts his penis into a female's brown eye, then proceeds to titty fuckthe lady, leaving remnants of shit from her own ass on her chest.
I gave Shannon a shitty titty and then kicked her ass out because she had her own shit all over her tits.
Not necessarily a "titty that is shitty" but actually used to express anger or frustration. Most widely used when something doesn't go your way or you hurt yourself but most common in extremely chill environments such as in a housey or on a boat.
John: Jimmy just got absolutely raped. That's too bad.
Nick: Shitty titty...
