(N.) BAW-stun CHILL-ee dawg. The sexual act wherein which a male defecates onto a female's chest, where she then squeezes her breasts together so that the male may insert his penis between her breasts, creating the illusion of a chili dog. The act is sometimes topped with semen to add a cheese effect.
As the couple made love, she lovingly looked up to him and asked for a Boston Chili Dog, with cheese.
