A new viral std whereby just watching a Lady Gaga video will cause you to contract it. There is no know cure for h-gaga except for suicide. Symptoms include random babbling of incomprensable lyrics, major depression, deep felt desire to dance with no clothes on, uncontrolable salavating, a rash that will develop legs and walk away, tunnel vision, erectal dsyfunction, hypertension, loss of talent, and a deep rooted desire to become a transvestite.
John was watching MTV and the new Lady Gaga video "Telephone" came on. He was unable to turn it of before contracting h-gaga. This in turn caused him to loose his mind, drink a box of Franzia, ride a mountain bike down some stairs, got a sex change and killed himself.
