Scud with the meaning of being person or persons unclothed and jotter being a thin paperback book.
So a thin book with pictures of naked people, chiefly women... Typically
available from newsagents top shelves or
from behind the counter.
My mum found my stash of scud jotters
yesterday, bitch made me return them to the shop...
Luckily
on the way back I found another scud jotter which had been thrown
in the bushes so I'm sorted for a wank mag.
