literally, a person who bites his/her fart bubbles in the bathtub; figuratively, one who engages in meaningless pursuits; one who seeks questionable gratification thereby; one who can't get enough of his/her own products (e.g., writings, videos, comments, opinions, recordings, etc.) and/or laughs at his/her own jokes.
Sheez, Dan, you're such a gzorp! Your joke fell flat because it was lame--did you even notice that no one else was laughing? Of course not! You were laughing too hard yourself!
