Indian Firehose
When you fuck a chick in the ass so hard her anus gapes, and then you proceed to take a shit in the gaping asshole, then when it closes, enema her, thus expelling all of your shit and any shit of hers out her butthole in a glorious explosion of brown. Named because of bad water quality in India.
I did the Indian Firehose with Tina last night, nao my apartment is covered with liquid poo.
