When a breastfeeding infant's latch on the breast is interrupted, they sometimes breathe out through their mouth. With their mouths pressed against the breast, this can make a wet flapping sound akin to a belly fart. This is known as a raspberry milkshake.
"Little Timmy slipped off his latch and blew a great big raspberry milkshake on mommy's boob. Now he's got milk on his nose."

A term for a woman with a little "more to love", used by Pete Holmes in his Somebody Loves Your Body monologue. A thicker milkshake is someone with a little bit extra on her, but not so much as to look overly fat or unattractive. Can be used in place of thicc or curvy, though each have slightly different meanings.
"My friend Sara has got a great body, she's what I call a thicker milkshake; I love a thicker milkshake! That's just more milkshake!"
