One of the non-slang meanings of "dump" is a special place for depositing garbage or rubbish (also called a "rubbish tip"). These places are usually smelly, messy and dirty, and the slang meaning of "dump" seems to have originated from the word being used metophorically to mean any place that's like a rubbish dump.
That bar we went to last night was a dump. It was
- dirty and run-down
- clean and well-decorated
- full of interesting people
