Tweeny Burger 

An adolescent that expresses extremely irritating qualities such as unnecessary screeching, attempting to revive dead memes, and lacking basic intelligence and maturity. These qualities can be represented through the analogy of a burger; just as many components come together to create a good burger, many irritating components coalesce to become a tweeny burger.
