Home made log book carried by police officers out in the field used for recording contacts with potential evil doers and criminals. Sometimes called a field identification logbook.
Turd Surfing occurs when you surf a local jettie, or water outlet, where water drains from the streets, into the sewer, into the riverbed. Ever notice why the water is always warm? Yeah, thats poo and pee. Ironically, the surf is usually always good, near turd surfing locations.
"hey fuckers, stop dumping shit in the street drains, no one likes to eat a peice of poo when they go turd surfing"
To keep it blatant, someone who breaks into your house while you're sleeping, tip-toes into your bathroom, reaches into your plumbing and steals your poo, stores it in their mouth or shirt, and scuttles out without being seen. Creepy poo thieves.
