Let me explain, I have an apartment with a great view; I cant help but bring it up in every conversation and every time someone inquires about how life was in Trivandrum. I could excuse myself saying, I was annoyingly proud of my balcony view.
I was boastful about my balcony view
I was smug about my balcony view
I think the sun shines out my ass (or butt, backside, etc.)/outta me anytime I speak about my balcony view Ngram
think the sun shines out backside
To believe a person is better or more important than others or above reproach. Various slang and vulgar synonyms for "backside" are often substituted. (Note: If thought about oneself, it means that he or she is arrogant, conceited, or self-absorbed. If someone thinks this of another person, it means that he or she loves or admires that person to such a degree as to be blind to any of their potential faults.) Tom has acted like he's such a hotshot after getting the promotion. He thinks the sun shines out his backside! He's absolutely head-over-heels in love with Mary. Even though I find her a bit irritating, he thinks the sun shines out her backside. Farlex Dictionary of Idioms
Many things become annoying when they exist or are done in excess. Excessive pride and being excessively proud are examples of this and there’s even a single-word adjective for it:
“Overproud” = “Excessively proud.” (from The Free Dictionary by Farlex)
A few choices would work:
swollen-headed, big-headed or puffed-up.
These all mean 'full of yourself'.
Conceited or vain
con·ceit·ed (kən-sē′tĭd) adj.
Holding or characterized by an unduly high opinion of oneself; vain.
