Okay, had to look that up. From wikipedia:
Chef Andrew Zimmern compares the taste to "completely rotten, mushy onions."[24] Anthony Bourdain, a lover of durian, relates his encounter with the fruit thus: "Its taste can only be described as...indescribable, something you will either love or despise. ...Your breath will smell as if you'd been French-kissing your dead grandmother."[25] Travel and food writer Richard Sterling says:
... its odor is best described as pig-
****, turpentine and onions, garnished with a gym sock. It can be smelled from yards away. Despite its great local popularity, the raw fruit is forbidden from some establishments such as hotels, subways and airports, including public transportation in Southeast Asia.[26]
Other comparisons have been made with the civet, sewage, stale vomit, skunk spray and used surgical swabs.
YUM!
