I am looking for a word similar to pompous or haughty. I thought of it for a while, and could not find a word that fit that description. It's also similar to tooting your own horn too much.
a slightly annoying form of behaviour, especially in sport, that is intended to attract attention or admiration because it is very skilful:
When he scored his fourth goal of the afternoon, we were forced to forgive his showboating and other antics.

Also parading. One of the definitions in American Heritage of parade is
To exhibit ostentatiously; flaunt: paraded their wealth.
For the sense of vainglorious boasting, with an upscale twist toward haughtiness, I like the verb
which dictionary.reference.com describes as an American coinage marrying blow (as in blowhard) and a Latin-like inflection. The source states that the word was favored by US President Warren G. Harding, for what it's worth.
Higher still on the scale is rodomontade, a word I keep on a special shelf for dispkay, and hardly ever take down and use. It's a noun, of course, and means bloviating, only a tarnation louder. Our friends at dictionary.reference.com offer this interesting history to this 17th century blast:
1605-15; < Middle French < Italian Rodomonte, the boastful king of Algiers in Orlando Innamorato and Orlando Furioso + Middle French -ade
Got to love it.
Boasting: a statement in which you express too much pride in yourself or in something you have, have done, or are connected to in some way (Merriam-Webster)
"We were offended by his boast that he would easily beat us."
Crow over: To exult over a victory or accomplishment; to boast or vaunt. The allusion is to a gamecock’s exultant crowing after defeating an opponent. This expression dates from 1588. (The Free Dicitonary)
"Alive, the question would be whether, being the victor, he would not crow over me."
