Retardation; v. the incorrect past tense spelling of the word "spell" often used by white trash, fuckjacks, hilljacks, the occupants of trailer parks, hillbillies who have learned to read and write, rednecks, and the imbred.
Recent defenses of this word have been used such as, "it's on dictionary.com!" Because, you know, if it's on the internets it HAS to be true.
"Spelt i jus az correctly used az speeled you dumbasses GOSH!"
To which one is required to rebuttal with, "I fear for our future, I really do."
"Ah'm a fukkin dumass an' Ah jus spelted dat on da innernets. Yee haw!"
