You might wanna check the accuracy of the place you got that definition from, because that's not what punk means, at least as far as I know. I think the place got confused with the T.V. series 'Punk'd', a show about pranking celebrities (at least it used to be back when I watched it, dunno anymore). The word you're looking for is 'prank'. The example sentences you written, replace 'punk' with 'prank' and you've got examples of the word being used in active voice. If you want to use them IN passive voice, here's an example, 'The teachers got pranked when they were least expecting it.' Hope that helps :)

the verb "prank" is the more commonly used term by far. I recommend sticking to that. I have only ever heard "punked" used in the passive voice. "Pull a prank" is the full phrase, but it has been shortened over time just to "prank". "I am going to pull a prank on my brother", "They pulled a prank on their teacher"

Punk'd was the name of a TV show where they pranked people and they would say "You got punk'd!" but it's never really used outside of the show. Like Michael says, it's best stick to "prank". (Edit: Ah sorry, I was supposed to post this as an answer not a comment... whoops :P )
