OYS or O.Y.S. is the acronym for "old yeller style"; it is an adverb used to describe the method with which an interpersonal relationship will be managed. Usually refers to a work/professional/social networkingrelationship, specifically office nemeses and incompetent staff.
This follows the same meaning as “kys”(kill yourself). The “o” is switched for the “k” so that Roblox doesn’t hashtag it. The “o” being “oof”. Oof means death in the video game Roblox so switching the letters let’s players say oys whenever they get mad.
