(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.
