A person who does something that they once fervently mocked you for doing.
Last week:
Steve: Dude -check out Angry birds, its so fun and addicting!
Jay: Phone game apps are so stupid -who has time for that crap?

This week:
Jay: I played Angry Birds last night till 2 AM!
Steve: You are such a mocker focker!
