A performer who gained (somehow) massive amounts of popularity in the last few years by releasing slutty songs of absolutely no musical value and espousing horrible "fashion" that is mostly spandex and large sun glasses on a pale, curveless frame.
Probably a man, Probably named Steve. This would explain the huge support mister Gaga has garnered from the gay community. Even if it's not a man, lets face it people. Lady Gaga is a flash in the pan, she can't sing, she has no body and her "fashion" is a laughable parody of something Madonna did in the 1980's.
