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.
