A pun on "wishful thinking," it's when a woman lets her own sexual interest in someone strongly color her judgement regarding the person's reciprocal interest in her. It makes her interpret every gesture from her object of interest as a come on, even when it clearly isn't. This is known as dickful thinking if it's a man.
Her: "So my one night stand from 3 weeks ago hasn't called me, even though I gave him my number and my email. He didn't give me his real name or contact info, but he mentioned he was a professor, so I looked through the online faculty profiles of every university in 100 miles, and found his picture. I think he'd like to see me again but just lost my contact info. Should I email him at the work address I found on the faculty website, or just show up and surprise him after one of his classes? I think he'd like being surprised like that."

Friend: "No he wouldn't. That's a bunch of clitful thinking there - let it go."

Her: "Suzy hugged me last week, so she's definitely into me. Her husband isn't at the party, so I think I should try and make out with her."

Friend: "That's clitful thinking. She's not hitting on you."
