Echobrocation is a fine tuned sonic ability that fraternity brothers seem to adaptively gain once they are well established in their respective brotherhood. In party settings, the frat males environmental niche, one brother will yell out a short nonsensical phrase that other fraternity members are sensitive to, and upon hearing, will repeat until all others have joined in. The reflected verbal phrasing is essential for pinpointing other bros locations in the hot, dark, hostile environment that is a frat party.
Classic example of echobrocation at a party:

Joey (yelling after hitting last cup): wattttaaayaaaaagottt !!
...

Chad( Loudly, from next room): wattawattayagottt!!!

Randall (From upstairs): waaaaaaaatayagotttt sonnn!!!!

Get the echobrocation mug.
Can be used when entering a brocation, to locate any other bros that could possibly be in vicinity.
The entering bro calls out any variation of bro, and if there is a bro in the vicinity they respond with another variation of bro.
