Genderfunny

 (also known sillyman gender) is a xenogender related to being a silly little guy, and general lightheartedness.

It's assumed that the use of "guy" is casual, and refers more to masculine feelings, rather than maleness exactly. This is supported by the stripe meanings of the orignal flag.
