look up any word, like cleveland steamer:
Spigning is the process where people will create spoof versions of traffic signs defined in the Traffic Signs Regulations and General Directions 1964, 1981, 2002 and 2011. The word is a portmanteau of "spoof" and "signing".

People who create them are called "spigners". often use software such as Photoshop.
