When Chachi first appeared on the series in season 7, he had a strange catchphrase that caught on, particularly with teenagers. What was it?

Out of all the girls that Chachi came across, he preferred Joanie, and would use the "wah wah wah" catchphrase when she was around. It wasn't until the middle of season 7 that Joanie started to see Chachi's charms, and we all know that the two ended up together, and had their own sitcom.
