Humpbacked swamp donkey is an excruciatingly ugly person. Normally associated with the the female gender and an extreme example of swamp donkey ie there are many men who will tackle a swamp donkey especially after a few bowls of loud mouth soup but only a rare breed will take on a humpbacked variety
"Jesus I was so steaming I pissed myself last night", "you must be so embarrased", "not as much as the time when you caught me shagging that humpbacked swamp donkey"
A large male, who's primary function on any particular night is to "tag and bag" and/or otherwise Remove all swamp-donkey's from the room, thus enhancing the safety of all other males/females in the club.
A less than hygienic person with low morals and of poor character, will do any sexual act ,steal,lie ect. for drugs.
Can not be trusted but always friendly.
Persons tend to be loud (like the braying of a donkey) and starved for attention. They tend to stay stuck in the muds, meaning they get nowhere in life or of use to anyone other than sexual pleasures.
