The Badge

The Badge is a symbol of jockliness. However, it doesn't necesarily prove that one is a jock, it is simply an identifier of one who claims to be a jock.

Badge Properties
The Badge isn't an end-all proof that one is a jock. A jock doesn't necessarily need to wear The Badge in order to be a jock. In fact, if one acts in a manner unbecoming of a jock, The Badge seems to entirely lose it's power. One's jockliness, and thus the integrity of The Badge, can only be restored by completing an act of pure jocktitude.

Todd's Jockliness
In "The Quarterback", the validity of Todd's jockly stature was put into question when he hesitated to aid in The Nerd's wedgie. Brad immediately questioned Todd's jockliness.

He asks: "Are you really sure you're a jock? Is that what you think? You think you're one of us just becasue you wear The Badge?"

To which Todd replies: "I don't wear a badge."

Todd is only able to restore his jockliness when Brad requests that he wedgie The Nerd himself. So in an act of pure jocktitude, Todd wedgies The Nerd and restores his credibility as a Jock.
