The word djent is used to describe the guitar tone made when a two-octave power chord is palm-muted. Bulb (a.k.a. Misha Mansoor) says it best: " the onomatopoeia of a heavily palm muted distorted guitar chord which is usually played as but not limited to a 4 string double octave powerchord, and as a result sounds much more metallic and sonically present than a 'chug' 'chugga' or 'djun' per se, and which is basically how Periphery would describe its palm muted guitar sound." Lately, the word, coined by Fredrik Thordendal of Meshuggah, has also been used to identify bands that incorporate this in their music. Some would argue it is growing into a genre of its own; others disagree and go by Bulb's definition, or refuse to use it altogether.
