The trope is a generally short-term, one-time incident where a character passes out after victory; they don't suffer any lasting effects once they wake up.
If renamed, "Post-Dramatic Stress Disorder" could be reassigned to Freak Out!, which is about about long-term, trauma-induced, emotional/psychological disorders — and even mentions post-traumatic stress disorder by name.
Freak Out! is also up for rename on claims of misuse; renaming this trope could hit two birds with one stone.
Out of 70 wicks, only one or two were actually misusing the name; no one's provided any evidence of it being misused/fixed in the past either.
