Every time the Olympic games come around we have people publicly gritting their teeth over medal and podium used as verbs. These people need to ease up before they have to endure a lot of expensive dentistry.
Medal and podium are not all that novel. Stan Carey has googled (another noun recently verbed) that medal, a verb for earning or receiving a medal, has been around since the early nineteenth century, in military contexts. Athletes took it up as far back as 1966, according to the Oxford Dictionaries website. And Language Log and other sites indicate that podium, for earning a place on the winners' podium, has been in use since 1992.
If they leap out at you from the page or the commentary, it's because you don't encounter them outside the context of sport. Virtually all activities develop specialized vocabularies, and it's usually idle to object to them. Medal and podium will go away again once the games are over.
Moreover, this shifting back and forth between noun and verb or other parts of speech is a perfectly ordinary linguistic phenomenon. There is even a term for it as a literary device, anthimeria, from the Greek, of course: anti, "instead of," plus mereia, "a part."
Open a dictionary at random, and it will be easy to spot common words that have shifted from one part of speech to another. I just did and found mete as verb, "to allot or distribute," and noun, "a boundary or limit"; meter as noun, "an apparatus for measuring," and verb, "to measure"; method as noun, "a way of doing anything," and adjective, "using the Method" in acting; metro as adjective, "metropolitan," and noun, "subway."
If you don't have a dictionary at hand, you can have a look at one of the many internet sites that list words serving as both noun and verb.
You may think, as Calvin of Calvin & Hobbes does, that "verbing weirds nouns," but in carping about it you are merely objecting to an entirely natural, and commonplace, feature of your language.
Perhaps you could buy a bite guard.
