An internet meme. Usually shown in dolanduck comics which are great comedy. It's also said by idiots who present them selves with as trolls and disgrace themselves. I can understand dolan duck comics stating "y u do dis". But when a person says it it's incredibly idiotic. They honestly make themselves look like fools in front of everyone.
