Ergo, you are accusing Dan Savage of cyber bullying Rick Santorum. Ergo, you are siding with Rick Santorum. Ergo, dave420 has correctly called you out for what you are.
Yes I am accusing Dan Savage of cyber bullying Rick Santorum, while I also see it as protected speech. What do you call such actions? Well, beside something along the lines of 'turnabout' or 'fair play' and simply 'satire', as none of them are specific enough. Wikipedia calls it a "Neologism" but that simply describes a new recent word rather than how it came into being used. "To Savage..." seems too vague for me and would be more of a push-back on it's creator. Don't get me wrong, I'm not calling to prosecute Dan Savage via the latest cyber bulling laws, but there has to be a good name for an activity which is 'An effort to punish someone by using the internet to make derogatory meme of something personal to them'. Whatever you call it (revenge?), the result of this particular turn of events will likely this new meaning for 'frothy ass mixture' will stay in our language, whereas Senator Santorum himself will fairly quickly fade from view (He's major asshat IMHO, with plenty to criticize without ever resorting to name-calling)
In fact, I'm surprised that he appeared on the national stage at all. The only thing that he was really know for nationally was about how Dan Savage singled him out for years of mocking for some bigoted speech on the Senate floor (like it was the first time a Senator said something stupid in that forum). While few people would make the association, but I would guess that without the additional attention of that particular neologism, the former Senator who failed miserably in his attempt at a third term might never have been even notice at the national level.
Do you realize that all the best slurs are usually started or propagated originally from within those same communities? I guarantee that within a couple of years, if not already, the people most using Santorum in language will be full on bigots. (e.g. "I see that some S@nt0rum leaked out on your pants) It might be news to you, but I've found that reactionary loonies don't care about irony, in fact they seem to relish in it. Also, it's likely that children who's last name is Santorum (or even rhymes with it) will see endless teasing for that 'offense', weather it be the descendant of a singular bigot who offended Dan Savage so deeply or not, it's still a lousy thing.
That being said I would support Dan Savage over Rick Santorum on virtually any other subject and if he's able to turn some of his notably into his 'it gets better campaign', I would argue that at least some good has come out of it.
