what does "purty" means ?
It's a humorous or derogatory spelling of "pretty", which implies that the speaker is unsophisticated. Mispronouncing "pretty" as "purty" /'p@rti/ (see [[SAMPA Chart]]) is similar to mispronouncing "nuclear" as "nucular" /'nuwkj@l@r/. Such pronunciation has even become standard in the case of "iron", which is pronounced "iurn" /'aj@rn/ even by educated speakers.
