(phrasal verb) When you're "fritzing out" you're losing your
grip on objective
reality and paranoia is kicking in. You think others are plotting against you and so you take decisive action them thereby increasing the likelihood that
people really are plotting to get rid of you because you're insane.
Trump is totally fritzing out. He thinks that the
people closest to him are secretly plotting against him. That's why he
fired James Comey and Sean Spicer and is
tweeting against Jeff Sessions.
