Due to the Empire of the United Kingdom in the 1700s and 1800s, and the sometimes-forced worldwide influence of the United States, English is the most widely-spoken language. But I certainly wouldn't call it universal.
Both Spanish and Chinese are gaining ground, but do not yet come close to English in number of speakers, either as a primary or secondary language.
Philosophically, 'redneck' type of speaking might be the most universal. By 'redneck' I mean a distinct semi-dialect within a language, used mostly by the 'unsophisticated' members of the population in any language area. This phenomenon is present in almost every culture and language group big enough to have pockets of population.
