Can you help resolve this question my co-worker and I are having?

I say the correct term is “Getting diggy with it.” I say it’s a take off of “I can dig it.”

She says it’s “Getting jiggy with it.” I say ‘jiggy’ doesn’t even make sense! like diggy does!.. :)

The winner gets a free pudding cup. As you can, this is quite a serious issue! Please help!
