Seriously, can anyone translate this?

I was just looking at the TV Guide listings for this evening, to see if there’ll be anything worth watching, and I saw the following summary for an episode of “Jersey Shore Family Vacation”:

It’s clap back season when the roomies go all HAM on the cooch who harasses them at the bar.

What language is this? The words seem vaguely English, but… Are “clap back,” “HAM,” and “cooch” some modern slang that I’m too old and uncool to know? Can anyone translate the sentence?
