A wingularity is created when the density of win in a certain area increases to the point of complete collapse, at which point everything around the wingularity is pulled toward it and converted to win. Wingularities are present anywhere everyone is having a gratuitous amount of fun and/or doing awesome things. They are rarely observed in the present, instead being seen through the occluded nature of the next day's hangover. Naming a wingularity during the present may tempt an intrusion from the failboat, the only object known to nullify a wingularity.
The wingularity is an analog to the singularity of astrophysics.
