A Knacker Flap is the large flap of skin prevailing from the gut that hangs over a males genitals, making them completely invisible when naked. The sighting of a Knacker Flap usually occurs in older obese men, and is usually tucked into their shirt. It is the male version of the "gunt" which is that of a female Knacker Flap.
Holy shit, that dude's got a mean Knacker Flap!
Omg is that guy naked? Where's his privates? Oh they're underneath his Knacker Flap.

Get the Knackered Mackerel mug.Exactly as above. A British expression. A place where an animal carcass (or carcase, depending on your dictionary), usually a horse (this is from way back when people still kept them within city limits, before automobiles took over) was disposed of and turned into glue. To be "knackered" is to compare one's self to being dead, exhausted, etc., often in a post sexual context, but any kind of tired will do. It is an allowable expression on the BBC. It has nothing to do with being injured in one's private parts, and there's many words for that, already.
