Charging a lot of money on a credit card shortly after paying it off in full is not a smart thing to do and so someone who is proud of themselves for doing that is being ironic.
Context: I racked up a lot of money on my credit card shortly after paying it off.
Hypothesis: I am so proud of myself since I charged a lot of money on my credit card shortly after paying it off in full.

Is the hypothesis incorrect? (Yes, no, or unknown)?
