The questionable path names marked over both Shorne Woods Country Park and Cobham Woods seem to originate from a single user (Urbanlung), who seems to have a history of this behaviour. Some of their more obscene edits to Cobham Woods appear to have already been marked as vandalism and reverted.
I can also say that there was no physical sign of such names existing when I last visited here (2024) - unlike the well-known and signposted "Cardiac Hill", which is very much a real path name. The area is otherwise well signposted for walking routes and bridleways.
