To be perley is to synonomize the definitions of the words "spotless" and "attractive", implying wide desiration among the opposite sex. More of a ebonical term than anything, the word perley has garnered most of its usage from the black community.
I.e. so we went to the bar and my buddy matt was so perley with the girls, he didn't have to buy a drink all night.
I.e. that guys perlier than brad pitt in a room full of single women.
