A Tom Hank - A way to say thanks, but it sounds like you just shot someon

A way to say thanks, but it sounds like you just shot someone.

I said 'A Tom Hank' to my friend and he thought I was mad.

My mom said 'A Tom Hank' and I thought she was yelling at me.

I did a 'A Tom Hank' in the middle of dinner and my dad sent me to my room.
