Anti-claus 

Leader of the forces waging war on Christmas.

Anti-claus dropped an IED down my chimney Christmas eve, but the package smelled of hummus so I didn't open it.

anticlass

The opposite side of the spectrum from class, yet no less valid. James Bond is class, with a slick haircut, a shaken martini, and a gold watch. Jimbo the karaoke king is anticlass. He's got a mullet, a Miller High Life (champagne of beers, come on!) and an Indiglo from Wal-mart. To Jimbo's constituency, his brand of class (anticlass) is just as great as James Bond's peers find his classic form.

I brought a 40oz Old English to the party last night and felt the poster child of anticlass.

AntiCausticosis

The event where mushrooms, through an error in their natural biology, emit a caustic acid. This acid, although related to Caustic Soda use in refinieries, has the reverse effect of Caustic Soda. It is a rare phenomenon. The mushrooms has usually been exposed to a higher than normal dose of radiation or an irradiated substance. Irradiated fungicide will usually cause this. It is recommended that if you are to venture near these mushrooms, wear a radiation suit.

An example for Anticausticosis is not needed here.
