Variations of:
"Hey can I get back that $50 I lent you? I always pay you back and thought we had a mutual understanding, what gives?"
"Nice whataboutism, quit trying to make it about me."
Also your example isn't even whataboutism which is defined as "the technique or practice of responding to an accusation or difficult question by making a counteraccusation or raising a different issue."
What other accusation or difficult question is being raised in your example? It's person A asking for money he lent to person B back and pointing out what when person B lent him money he paid it back.
That's why claims of hypocrisy against the other party, backed up with examples of the same behavior in other situations from them instead of you, can be cheaply dismissed as "whataboutism".
However... visa V mastercard , using whataboutism is valid in this situation. Bringing up something the US government did in the past to silence the criticism of a US citizen to another countries actions is wrong.
EDIT: Just another thought about your example. There isn't even hypocrisy. Person B lent money to A and A paid it back, then Person A lent money to B and B didn't pay it back.
- B doesn't pay back money
- A pays back money
There's no contradictions in their actions.
What has this parent done that makes them ineligible to criticize others?
It's a method of deflection.
"Whataboutism' is a rhetorical device that involves accusing others of offenses as a way of deflecting attention from one's own deeds."
Whataboutism: "the technique or practice of responding to an accusation or difficult question by making a counteraccusation or raising a different issue"
Hypocrisy: "the practice of claiming to have moral standards or beliefs to which one's own behavior does not conform; pretense."
You can't be a hypocrite for something another person, group, or country has done. Even if you are a member of that grouping*. Notice how the definition clearly states "one's own behavior".

* I'm sure there's an exception here if you represent that group or control that group, like the CEO of a company or a spokesman. However just being a citizen of a country doesn't apply.*
Are you bloody serious? For real real not for play play? Some other poster made the comment that "whataboutism" is deflection. Considering every country has done some amount of bad things, either in the past or now, according to you and other parents, no one would be allowed to criticize any other country's govermnet. That's the ultimate deflection.
