my fellow Philadelphian colleague and i were discussing the Rita's Water Ice jingle when to my horror our Brooklyn-raised co-worker said "What's Rita's?" which then prompted me to google "wooder ice" because you know, that's how we roll on the east side (of PA).
here's what i got:
the Urban Dictionary defines Wooder Ice as "the Philly way to say water ice" and used in context, the quote is "you get your free Rita's yesterday? damn that wooder ice was good"
