Grumbleweed 

The various nefarious adult publications found ripped up underneath bushes/hedges at bus stops and public conveniences etc. (Pregnant Asian Babes, Razzle, Hairy & German)

Named after the hugely popular 5 piece comedy showband of the 1960's onwards.

'I alighted the bus to discover a small pile of disgarded grumbleweed on the roadside. Not only had the vibration of the bus journey aroused me, It now seemed that the aforementioned publication had provoked a small droplet of sperm to emit from my bell end'.
