The man in Södertälje just south of Stockholm attempted to register a custom plate reading "A55ORGY" (we'll leave it up to readers to interpret that), but the Swedish Transport Agency (Transportstyrelsen) rejected it on the grounds that it could be considered offensive.
The man, who wished to remain anonymous, told public broadcaster SVT that he was inspired by a family member.
"My cousin in the USA has a similar one," he said. "It's a shame I got a no, but I'll come up with something even smarter."
Transportstyrelsen's rules state that a personalized plate "may not be designed if it causes offence or harm to anyone else," including allusions to alcohol, drugs, sex, swearwords, religion or criminality.

Plenty have tried to get cheeky combinations past them regardless however, including some who were slightly more creative than the Södertälje resident in their efforts.

A man in Nässjö meanwhile had a slightly more tame plate containing the combination "RUMPA" (‘butt' in Swedish) rejected in June.
