Small penis humiliation, a fetish people are into (usually men, in rare cases... trans women), where they get off by someone calling their dick small and/or holding up their pinky, or making the "tiny" gesture with their hand.
This may resemble Britney Spears because it's based on her. It refers to any talentless hack who doesn't deserve success and adulation, even while doing whatever shameless thing it takes to command unwarranted attention and/or stay in the public eye.
