Delusional Dave: A person that does not take hints of dislike, but in turn takes them as flirtatious motives.

Started by several redditors.
Amy: Frank was being such a delusional Dave today. I told him I wasn't interested, he thought I was playing hard to get and walked me to my car.

Julie: Oh my god, I told frank to lay off, he pulled a delusional Dave and said "She just wants me to prove my love"
