yy

Short for "yeah yeah". Is a disrespectful response/way to end a debate, if you had enough from someone and are not up for further discussion at all.

Its usually not a comedic response, unlike the long version "yeah yeah" can be. Since it expresses how annoyed the responding person is, by them not even bothering to type out the full words ("yeah").
