Porno mags left in the hedges and brambles by fleeing teenagers or kind hearted perverts, normally for other teenagers or perverts to find.
Sometimes the best way for a teenage boy to learn about porn. Sadly in decline due to internet porn being so available.
"Wow, I found the biggest stack of bramble mags today, out near the old folks home. Most of the pages are still clean."

"Lets go hunting bramble mags."
"Nah, we'll just go on pornhub"
