To turn something into a character from the animated tv show, my little pony friendship is magic. Often used on fictional characters. E.g turning Mario into a pony. Usually rule 85 of the internet states: If something exists, there is a ponified version of it, no exceptions.
To be over dressed 'as a ponce' especially if one is ordinarily rather conservative in dress. Applies mainly to men. Not a compliment but an observation, sometimes with negative connotations.
eg a man dressed in a suit and tie for a date or interview and wearing sftershave, when he normally dresses casually and is unshaven, is an example of someone who is 'poncified'.
See the film 'Alfie' starring Michael Caine, where the word is used.
Look at you all poncified. Where do you think you' regoing? Buckingham Palace?
