look up any word, like bukkake:
The term used to describe a person who will constantly describe themselves or their achievements in a favorable light. To give yourself a verbal blowjob. From the word fellatio, meaning "oral stimulation of the penis", and the word self, meaning "one's identity."

Opposite of self-defecating.
People who exaggerate their achievements are self-fellating.

"I totally scored a 10 last week."
"Dude, she was a six. You're self-fellating."
