A chewy, stringy piece of latcation that comes out of a girls nipple.
Ian: "Dude i was sucking on this girls titty last night and i got a mouth full of milk worms."

Lewis: "Dude thats nasty as fuck. Why'd you tell me that?"

Ian: "I don't know. I kind of liked it."

Lewis: "Fuck that."

Get the milk worm mug.
