look up any word, like guncle:
The combination of Jonny, which simply means condom, and Purvis meaning pervert, it is a person that perverses over people, but does use a condom. This is quite a new era of perverts, but is a step up from the original non-condom using perverts.
That lad has just gone and done a Jonny Purvis, that girl didn't see what was coming!
