In the middle of anal sex with a female, pull out and proceed to vomit in the gaping ass hole. Once done vomiting continue the anal sex until climax. The sludgy mess that escapes her rear afterwards provides your chili bowl with its contents.
all that is known about the texas chili bowl massacre is that it involves a telephone, hot sauce, the anus, masks, a carrot peeler, an eggbeater, a hatewhisk, an ice cream scoop, 4 parrots, the frozen corpse of buddy holly, a spatula, satan's ladle, 48 chopsticks, an inhaler, and a VERY slutty turtle.
When you've met a new female friend and bought her back to your place/hotel, after failing to score she takes a huge dump in your bathroom before saying goodbye and leaving.
Guy 1: How'd last night go? I saw you leave with her!
Guy 2: "Man, I thought I was certain to score, she got back and then said she was freakin' tired. What made it worse was she left me a fucking Puerto Rican Chili Bowl!"
