Glassman - as Allison P linked to, my source is Peakbagger, as well as listsofjohn.com, summitpost.org, and other hiking/climbing sources.  From what I can tell, the climbing community has used this name since the 1980’s, potentially the original source is a Fred Beckey climbing guide.  This name was given due to the peak’s ordinance between Bettys Pass and Jug Lake.  Definitely didn’t intend to add it as a prank!  As one of Washington’s 800 most prominent peaks, I just felt that the name should be reflected on OSM.
