What is I Can't Ride On That Love?
What you say when someone makes a promise to you which is unlikely to be fulfilled. Another way to say "talk is cheap".
Boss: I would love to give you the promotion.
Hapless: Yeah? Well give it then, because I can't ride on that love.
Jane: If you buy me a drink, maybe we could spend the night making passionate love.
Tarzan: Well, I can't ride on that love, so I am going to hook up with Cheetah for a sure night of animal action.
