</noinclude>Ronnie is Roseanne and Jackie's cousin who appeared in an episode of Season 5.
Background
Roseanne calls Ronnie "a jug". She is a wealthy, somewhat snobbish cousin of theirs who Roseanne seems to hate at first when Ronnie comes over to pay her respects about the loss of Roseanne's father, Al Harris. 20 years prior to the series, the two had a argument (or misunderstanding as Jackie puts it). Roseanne was supposed to be a bridesmaid at Ronnie's wedding but according to her, Ronnie thought that she wasn't "good enough" to be one. Roseanne called the wedding a "pretentious, overblown piece of crap!"
They eventually make up and realize how much they love to mock each other.
