The act of slapping one's penis against the forehead of the person who just performed oral sex on you to remove any jizz left in the shaft of the penis.
I always like giving her the thonker so cum doesn't drip on my underware after I zip up.
A wishful thinker is one who naively believes, what he/she wants an outcome to be, rather than dealing with the alternate reality of what the outcome probably in reality will be. Wishful thinkers are very sweet, but get into trouble with this way of assessing situations. Often very unrealistic, in a silly way. Pollyanna, optimistic. What they want to be true blinds them to reality.
