Equaloser 

In sports, a team where an over matched team inadvertently scores a point or goal, temporarily equalising the match against a far superior opponent. This incurs their wrath, leading to a humiliating and one sided destruction for the rest of the match.

Arsenal just scored an Equaloser vs Man city. The floodgates are about to open....

The Great Equalizer 

The technique of groinal destruction that eliminates any difference in skill and power levels between men and women when it comes to fighting. A swift kick or punch to the male crotch.

acoustic equalizer 

The art of smashing an acoustic guitar to pieces on ones head, thus producing a painful and comical effect.

My stupid friend accidently took a cd my guitar teacher gave to me, and then forgot to return it, so my guitar teacher, in a fit of rage, gave me an acoustic equalizer.
