Ebrolocation 

Similar to echolocation, however it's the method for white teenage boys to locate their friends while not within sight of each other.

BTW, this ACTUALLY happened, and is the source of this UD entry:

Biff: "Dude, where's Chad?"
Skeeter: "Dude, I think he was over in the Walmart shoe aisle looking for Shaqs"
Chad (heard faintly from across the store): "DUDE!"
Biff: "DUDE!" (moving toward the sound of his bro)
Chad: "DUDE!" (responding to the sound of his bro)
Biff: "DUDE!" (nearer to Chad)
Chad: "DUDE!! THEY'VE GOT SHAQS!"
Biff: "DUDE! NO WAY!!!"
My daughter: "Douchebags find each other using ebrolocation"
