When the sleeves of someones undershirt are embarrassingly exposed--giving a ruffle-esque appearance.
Dan is the resident anti-poon because he is always gleasoning--his undershirts are always two sizes too big.

the act of unintentionally having the sleeves of your undershirt exposed underneath a polo shirt or other outerwear.
I was going to ask Dan to the dance, but I saw him gleasoning in school one day so I asked Josh instead.

To immediately throw away something that you know you will not keep later. (related) To jenny gleason is to completely purge oneself of all but life's essentials.
Ryan gleasoned his yogurt lid medal immediately following the office olympics, despite Pam looking on, reasoning that he would eventually toss it later anyways.

The assholes' asshole. Actor famous for roles such as Principal Richard Vernon in The Breakfast Club and Deputy Police Chief Dwayne T. Robinson in Die Hard. He perfected the self-important authority figure until it became an art form which can be watched again and again. In real life he is said to have been a genial man who was quite unlike his famous roles.
Nobody plays an asshole better than Paul Gleason.
