"all these girls you see at the pubs holding hands & kissing eachother in front of large groups of people, it's like they have Tatu Syndrome"
Bits of ugly fat hanging over the top of hipster jeans when someone squeezes into a size too small.
Most visible from behind, the unsighly bulges can be spotted in almost any pub or night club in the UK on a Friday or Saturday night, and sightings have been reported during the daytime too.
The hipster jeans are usually accompanied by a tight t-shirt which rides up to the narrower part of the body due to the width of the plaps, making them more obvious. The t-shirt may also be a size too small, although this is not always the case.
"I have to keep pulling my t-shirt down to cover my plaps."
