To eject a thin squirt of saliva from underneath ones tongue. Usually directed onto someone else’s face unexpectedly. Unless you have “mate” who does it on purpose. A gleeker is also known to ambush you with a cupcake (fart in the hand). They are also proficient in the art of the stink finger attack. I think this “friend” may have invented the term “gleek” back in the early 80’s at school. He is quite possibly the guru of Gleekism.
