I was suggested Drop someone in it but I need a simpler phrase that is more commonly used.
You really "got him into trouble" when you "told on him" or "ratted on him" (slang). Those would be specific replacements for the phrase you linked to. "Set him up" works too, but that suggests that you are going to do something that gets the person caught doing it again. (Or you have done that - keeping the same tense)
The original phrase you linked to is not a commonly used phrase in the US.
Gaslighting: usual tactics in some families. Psychological abuse of distorting information (in other words, the truth), to create anxiety and confusion in which the victim questions their own sense of reality.
PNR (Point of No Return): used in aviation industry in reference to fuel levels in aircraft, obviously.
Euphemisms (notably military) are a good source too. Some examples: - Pre-emptive strike - Neutralize ('kill' the threat) - Target(s) of opportunity (assassination) - Surgical strike (use of guided munitions, or rumors in this case). - Area denial munitions (or in this case, a restraint order). - Friendly fire (on former friends and family members).
Resources are unlimited, just need to research a bit is all...
