MANglish Dictionary Needed

I had a date but he had to cancel because his child care arrangements fell through. Later in the day he called and said, "my mom said she'll watch my son." So I said, "I need my MANglish Dictionary, does that mean you want to see me?" and he laughed and said, "Yes."

It would have been more clear for me if he said, "I have arranged child care and I would like to see you. Can you still go out tonight?"
