A noun that may be applied to describe any male over the age of ten with oversized mammary glands, or a word to express one's anger, frustration, or sadness at an unfortunate event.
Wow, that dude has some major bitch-tits goin' on.
When literally a girl's tits are bitches...oh you thought this definition was gonna be that easy... well I don't think so.... But, okay. Basically, Bitch-Tits would mean mostly someone who is annoying or won't stop talking or in this case ever start. "SHUTTING THE FUCK UP." But, it can be commonly used for anybody and any gender or what have you. I certainly made this and have used it for quite a while.
"Look at Sharkisha, she's such a pair of Bitch-Tits, like Zayuuuuuummmuuuuhhh."
"Do you ever shut up Bitch-Tits?"
"Just stop with your Bitch-Tits."
