A slang term given to the annoying junk mail placed in the folds of your favorite newspapers or magazine. Aptly named after its closely related cousin, e-mail SPAM or its younger brother the internet "Pop-up". Demonstrates a similar surprise to pornographic internet Pop-ups however the surprise is generally related to the sheer volume of literature (approx. one tree worth of paper), rather than seeing your grandma gang-banged by the Collingwood Magpies, while you drink your Double Frappamappachino with extra froth in a trendy internet cafe.
Dude 1: Hey Dude, i was drinking my Double Frappamappachino with extra froth in a trendy internet cafe when i opened my newspaper and was crushed under the weight of an entire forest.
Dude 2: Yeah dude you got a good case of the lap spam
