A man who doesn't make it easy for a woman to have sex with him after he's been telling her for a long while that he is into her and when she finally agrees he inexplicably gets cold feet; The antithesis of 'a sure thing'; A man who would rather talk, sext, videochat, or exchange naughty photos with a woman instead of having sex with her in the real world.
"So did you ever hook up with that guy who's been wanting you for so long and keeps telling you so?"
"No, it turns out he's a total freddie! He was all talk and no action. Fraud!"
