Top definition
A type of party held by the fraternities at Penn State University which take place during the day. These parties usually start at around noon and last until everyone is either passed out or getting laid. Daylongers usually dress in ridiculous attire often consisting of brightly colored pinnies and hats. Most daylongs have a live band and copious amounts of Natty Ice. It is pretty much the best thing about spring.
The weather was getting warm so Meghan said "Its daylonggggg season!"
