Yet another slang term for breasts. Along with Boobs, Tits, Boobies, and Jugs. Coined by two very exhausted Bennington College girls working on their biology and stage management homework.
"I hate my Birbs"
"Look at that girl's birbs. They are huge"
"Oh my, my birbs are all wet. Ew."
"Guys, wouldn't it be great if you could like take out your uterus? Then people could like steal your uterus and make you try and get it. Then you'd value it more. Birbs."
