Plamf is a Scottish word used to insult people, or in the gentle ribbing of friends.

It actually means "one who enjoys sniffing another's underwear".

A cultural and aesthetic mind-state that prioritizes making money, even as an “underground” or “radical” creator. The work isn’t made for money, but it’s the money that matters the most.

Someone who sniff's underwear. Usually a pair of granny pants that have not been washed yet

In Glasgow, Scotland..

One who sniffs pants....a nicker sniffer.

Plamf is used when you can think of no other word to use or if you are bored and in need of something to say.

In Scotland, a plamf is a derogatory term meaning idiot. Depending on the context, you can use plamf as an extreme insult to passers-by, or in gentle banter between male friends.

Everyone else is wrong on here.
