A phrase in American English that, as a native British speaker, I may have misheard

I am a lifetime native speaker of British English and sometimes I don’t recognise phrases used by North American speakers. I can be unsure whether it is an unfamiliar phrase or whether I have misunderstood because of the speakers accent.

In this instance the phrase comes from a court-case I am am following.

This is what I hear the lawyer say:

Uh … Did you ever use the term uh … [inaudible] sickness. Have you
ever heard that?

14-CA v. BRODERICK: WITNESS TESTIMONY

The words occur roughly 51 minutes into the recording. (marked as 51:00 on the play bar under the picture). Apologies; you will get some adverts but they will eventually disappear even it seems like they might not!

Question

What does the male lawyer actually say?

I made the above transcription. I didn’t give my interpretation because I thought it would be a distraction. If you want to know what I believe he says then it follows below:
