If your teen is bugging you and won't let up…start twerking. Guaranteed to have them running screaming from the room thereby restoring peace for at least a few precious moments. 
If for some reason your teen is of a stronger constitution than mine and continues to pester and annoy offer to load a video of you twerking onto youtube and post on their Facebook timelines.
