dude partay 

Most likely to occur in a college setting, a dude partay, or DP, for short is a social gathering in which most (or all) of the people there are male. Dude partays are always unintentional and the lack of girls causes much disappointment. This is generally noticed upon initial arrival and regarded with disgust and often leads to rapid cell phone calls/texts.
*Note the 2nd "A" in "partay" is always emphasized in a sarcastic/melodramatic manner.

Mark: "Oh shit where are all the females"
Steve: "i fuckin knew it, dude partayyy"

Dude party hat 

phrase used to describe a "bucket hat" when worn by custies, mooks and f-ed up frat boys. In a crowd of beer guzzling abercrombie wearing mooks, there will always be one wearing the hat in question.

"Some fratboy threw his Dude party hat on stage at the Dave Matthews Band concert."

That dude with the guitar at a party

The douchey guy that always brings his guitar and tries to act cool at parties or other gatherings. The conversation always comes back around to the type of music that he and his band are doing now or why his taste in music is so much cooler than yours. When the focus turns to someone or something else, he starts to strum loudly on his guitar or tries to get other musicians to have an impromptu jam session so that he can be the focus again. This guy is typically one of two personality types; way over the top happy or the brooding "too cool for school" guy. For an example, see Reverend Tim-Tom from the TV show on ABC named "The Middle."

Your friend Ethan is turning into "that dude with the guitar at a party."
