This post from the Usenet newsgroup rec.arts.sf.fandom sums up the trope. Note: everything written about the Huntress' origin story here actually happened in the comic.
"So, what's your origin story, Huntress?"
"My entire family was gunned down before my very eyes."
"Big deal. Join the club."
"But it turns out they weren't my real family."
"Well, my mother was really my mother, but I was actually illegitimate."
"So was your real father?"
"The guy who arranged for the hit on my family."
"Well, at least you weren't killed by your own father."
"No, but I was supposed to be."
"The hitman was supposed to kill me and her husband, but spare my mother so she could marry my real father and they could start a family."
"So what happened?"
"The hitman got his Helenas confused."
(There is a stunned silence for a moment. Then the Punisher, the Executioner, and several other vigilante heroes look at one another for a moment before all throwing their money on the table in front of the Huntress.)
"Okay, you win."
"You've got me beat."
"And I thought my origin story sucked."
