look up any word, like jamflex:
 
1.
A state of mind entered, where a person reacts with a seething rage to all external stimuli, brought on by ill fortune or most often by an argument the person is losing. Symptoms include eyes closing over, reddening of the face, loss of rational thought and the increase in vocal volume coupled with an inability to speak coherently. Alcohol is often, but not always, a contributing factor to seethe mode.

Julian: yeah, he's definitely entered seethe mode
