This is a pretty pedantic argument. Great, I'm down.
Since this is a debate forum, I disagree because you're twisting the definition of regret into "I don't actually regret eating ice cream, I'm just complaining verbally because it's socially acceptable to joke around about this".
I'm reading regret as "I actually wouldn't do it again"
People don't "regret" eating ice cream. People do "regret" gambling their life savings away. Big difference
Your wording didn't sound like the colloquial, joking version of "regret"
again, respectfully, your interpretation of the word regret has no bearing on the established english definition.
