fritzing out

(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.

Fizzling. 

The feeling at the base of a penis just before ejaculation.
A sure way to know that
a) You've done your job and its about to be over
OR
b) You know you have time to escape the juices of love.

Sarah was blue in the face after giving head for four hours, when at last she felt the fizzling. She knew her work was almost done. She took one last gasp for air and sprinted to the fizzle line.
