Sideswipe has a list of nostalgic slang words from previous generations.
I had heard of or used dork, gripper, goober, wicked, grouse, rad, pash, snog, PDA, yonks, spack, spaz, munted, stink and choice.
Incidentially PDAs should be banned!!
Hadn’t heard the term mole patrol before, but pissing myself laughing at the term.
UPDATE: Nick Enyon has his own list of slang terms. Very funny.
