MEME REFERENCE

You know, I'm something of a scientist myself

Use for mock expertise or overconfident self-identification in a technical domain.

What it expresses: Self-appointed expertise: a speaker claims credibility with playful understatement.
Example: Someone changes one config value and immediately calls themselves a distributed-systems expert.
When not to use it: Avoid when the speaker is genuinely qualified or the joke is not about claimed expertise.
