WTF? Do you fools listen to my posts or do you just skim through 'em?
Undoubtably: The correct standard form of the word is UNDOUBTEDLY. He UNDOUBTEDLY says "undoubtably" in the song. There's a reason it's underlined in red on spell check, you know.
Sededation: The word is "sedation." Sure, he may have been saying it that way just to make it rhyme with "medication," but that doesn't change the fact that it's not actually a word.
Succame: The past-tense of the word "succumb" (which is clearly what he intended) is "succumbed."
Hydrocordone: The generic name for vicodin is "Hydrocodone." There is no "R" in it.
Aphyxiation: The word is "asphyxiation." The "s" is not silent in any of the forms of the word.
Intergalactical: The word is "intergalactic."
Conversate: The correct, standard English form is "converse." "Conversate" is what is known as a back-formation.
