Is referring to yourself in the third person super corny

Let’s provide some examples and expound on the likely need it serves.

“Good engineering is rare”

Another was something along the lines of

“Producers who design their own instruments are rare”

In the first case the individual is using a double entendre to speak to the finding quality audio engineering is rare. They are also complimenting themselves as they go by the moniker Rare. In this case when a person agrees with them (who only picks up on the first meaning) the narcissist takes it as a compliment to their abilities also. Considering themselves clever for their duplicitous use of language while at the same time considering others response to their words an affirmation of their abilities.

The second case has the same end goal.

they need to strap you in a straight jacket and lock u in a padded room in the bellevue mental ward.
