Adjective or adverb describing promotion of self or group one belongs to
Is there an adjective or adverb depicting self-promotion (or promotion of a group one belongs to)?
I am thinking of something that has a somewhat negative connotation, in the spirit of phrases
- patting yourself on the back
- shameless self-plug
A person who engages in shameless self-promotion is self-aggrandizing.
Merriam-Webster's pithy definition:
self-aggrandizing, adjective: acting or seeking to make oneself greater.
Exhibitionism (noun) is behaviour to make people notice you and is usually used with a negative connotation.
