A sugary, chocolaty, very tasty, mildly alcoholic girl drink for those who want to drink, but can't stand the taste of alcohol.
Dude, I can see your vagina from here. Finish that damn drink. It's a chocolate choo-choo and tastes like dessert.

That chocolate choo-choo is mainly made up of sugar and air, no wonder it's tasty.

Get the chocolate choo-choo mug.
The act of defecating on ones chest while wearing a conductors hat and having them yell "CHOO CHOO" while strangling ones throat and having ones canine observe.
John and I were making love when I suddenly felt a warm substance on my chest and I heard him yell "CHOO CHOO"!! I think he just performed a "Chocolate Choo Choo Train" because he was wearing his conductors hat and he made my dog Nibbles stay in the room.
