|1.||Toot my own dick|
A bastardization of the idiom "Toot my own Horn" but emphasizing a narcissism equivalent to wanting to have sex with yourself. Used ironically to brag.
Person 1: I don't mean to toot my own dick but I think this is the best painting I have ever made and better than what anyone else will ever make.
Person 2: Keep it up and eventually that ego will expand to the point it collapses and you devolve into an asshole.
