I cannot, under any imaginable circumstances, EVER see my therapist using the word tits in session. He once copied me and used the word boobs during a discussion and immediately apologized. We weren't talking about my chest, so I was totally fine with it, but he sprung right into action and said he should have selected better wording.
For all I know, he sits in his office and chants TITS TITS TITS when I'm not there.

But he'd NEVER say that directly to me. EVER.
I would run like hell. That sounds so freaking weird. It's giving me definite creep vibes.
