To pervert (v) is to twist something, often beyond recognition. Usage: "Creationists will often pervert science to bolster their case".
An act performed by a pervert is called a "perversion", or alternatively, "fun".
Many sexual acts which were previously considered perversions have become increasingly perceived as "normal." The list includes homosexuality, masturbation, cunnilingus and fellatio (Bill Clinton popularized that one).
