Gwash is the definition of being a type of weird. When someone calls you gwash it is a way of telling you that whatever you did was unique in a weird way. Being gwash can sometimes be a good thing, but not always. If you say something that is like a really bad pun then you may be called gwash. Or if you act weirdly you can be called gwash. The only time it may be a good thing is if what you are doing is funny, or what you have said is funny.
Dude that joke was terrible, did you make that yourself? You are so gwash. Don’t be gwash. The pose you just pulled was so gwash (hahaha) The gwashness of your joke was terrible
