When you take your penis and have sex with only a person's butt cheeks. Sliding back and forth like a hotdog in a bun. Eventually climaxing and releasing the spicy mustard.

During the act of anal sex, a man will pull his penis out of another mans anus and insert the poop covered wiener into the armpit of the reciver. He will then continue to make love to the armpit untill an ejaculation is achieved. At this point the man will ejaculate into his hand and rub it onto his penis. To complete the Chicago Dog the man will insert his poopy, armpit, sperm covered wiener into the mouth of the reciever.
