Tiddle Wink

When you are making sweet love to a girl and all you can produce is a droplet of cum (You are not a man)

Girl: What was that?
Guy: I only gave you a tiddle wink
Girl: I think we should see other people

Tiddling their winks

A way of saying someone is jerking off instead of doing what they are supposed to.

You can believe they were just a bunch of assholes sitting around tiddling their winks.
