The badge of honor affixed about the shoulder of a caring parent by a baby during burping. Like snowflakes, no 2 milk brooches are alike. These decorative regurgitation signatures are commonly gifted to the recipient prior to a special night out on the town. Some think that it is the baby's way of helping the parent look their very best just before departing. Sometimes a milk brooch can morph into a milk necklace, but we won't go there.
I was wearing an interesting milk brooch today on my favorite grey sweatshirt. It looked like an octopus swimming diagonally. I got several compliments on it.

First you cut a hole in the bottom of a popcorn bucket and insert a particularly small penis through said hole. Then you surprise your movie theater guest with it.
Tony went to the movies quite often with Medusa, but one time in particular he MILK DUDED the popcorn bucket. Not only did she not find it amusing, she didn't even find it.

The smocciest of milks, available only to those who have reached enlightenment and inted themselves to heights unreachable by those unsmocced
Bro 1: Hey bro got any smoccy milk?
Bro 2: Achieve it yourself man!
Bro 1: you know what, you're right

When your banging your girl and she reaches around to your ass, shoves her finger up your ass and milks your prostate at the same time. Produces intense orgasms and heavy loads.
May also be performed by a third party is one is involved like your girl’s girlfriend, your perverted uncle that likes to watch or your roommate lending a helping hand.

I was slinging ropes last night when I busted. She was giving me a courtesy milk.
Your mom is so kind braaaaahhhh. I can always count on a courtesy milk.
My uncle paid me $50 to watch me and my girl do the nasty. But he gave me a courtesy milk and now I’m kinda creeped.
My roommate walked in on me and Sheila going at it like rabbits. But I had him stay and give me a courtesy milk.

A horrible surprise. In order to concoct, you need a metal thermos, and a car. Place dairy products inside the thermos. Milk, cottage cheese, heavy cream, shredded cheese. Anything that goes bad with haste. Seal the thermos and place it in the back window of your car. A good thermos is airtight. Allow it to sit all through the summer, even multiple summers if you're patient. When the time is right, open it and unleash the vile stench onto the world, be it throwing it ON somebody, or into some jackass's convertible in a hot parking lot.
