A cute girl (usually smaller) with perfectly proportioned, round, perky breasts.
Did you see what she was wearing today? Trying to hide them perfect little muffintits.
Referring to any woman.
"Hey, Muffin Tits!"
"Did you just call me 'Muffin Tits'?"
"Yeah, because that's what you are, girl. A Muff 'n' Tits."
When a woman has breast implants and her nipples become extremely large, and become puffy
Rachel had a boob job last month, and damn man, she got some muffin tits.
Boob spillage, as in when a woman wears a bra that's too small, as in muffin-top.
I need to go bra-shopping this weekend. I've got a serious case of muffin tits today.
Where some of the breast is coming out the top of your shirt and bra. It forms a quad boob effect
Muffin tit is also linked to quad boob
"oo muffin tits! whereever did you go!?"
