Carolina Brown Bagging
(noun, can be used as a verb) The act of a male having intercourse with the stoma (hole) of an individual with a colostomy bag. Popular among street-walkers, who generally charge extra for such services, as it is often advertised as the "The Fourth Hole".
I got a hooker last night, who quoted me $10 for oral, $50 for a half 'n half, and $80 for Carolina Brown Bagging. Its extra because "it's such a hassle to reconnect the colostomy bag afterwards!"
