bloodfart
The unfortunate spackling of bloody pooh in ones underwear when attempting to pass gas. This is generally caused by being anally penetrated on a regular basis by large hairy men with names like Bruce or Greg.
Poor old Zink could not finish playing Trivial Pursuit, as he had inadvertantly let a bloodfart, completely soiling the insides of his skivvies. He was secretly relieved, however, as he was losing terribly, as usual.
Get the bloodfart mug.
