"Bull" as a rebuttal, meaning "nonsense" or "rubbish," is a bit harsh for polite society, since it always implies excrement. Even if you soften it by saying "bull twinkie" or "bull bleep," we know what you mean. Use "nonsense" or "rubbish."

"Slang" means informal, socially un-acceptable, vulgar, or playful. During WWII, Americans were often called "Yanks", short for "Yankees." In South Vietnam, nearly all US servicemen were called "GI." Both Yank and GI are slang words. During the US Civil War, Confederate soldiers were called "Rebs" short for Rebel, which in itself is short for "Rebellion" (because that's what the Confederates were doing...rebelling against the United States of America). The word Reb is a slang word. Whether or not the words "socially un-acceptable" or "vulgar", or "playful" depends entirely on whose offended by the word.
