A type of statement or act, whether verbal or physical, that conveys a sense of pride in honor of the
performance of said statement or act, that is by its nature cheesy, sappy, and excessive. A Guitar solo is
almost always followed with a "heh" or a noise or action with similar
exclamatory meaning.
More applicably, someone can actually "be" a guitar solo if they make a statement or behave in a way that has become so desperately conventional or standard as to render the statement or behavior cheesy, sappy, and excessive (think motivational speakers).
"Heh, gonna pick up Lisa later, take her for a ride in my Hemme truck and get
road dome heh."
"Heh, you city boys and your two-wheel drive trucks are no match for my Ford 4x4 and its killer towing capacity, heh."
"Dude, how many times did that speaker say 'in this economy' and mention how we needed to 'get er done' in order to get out of
the recession?"
"I know dude, that guy was such a guitar solo. I seriously just wanted to start playing the air guitar right in front of him."
"It's not about staying up, heh, its about
getting up after you fall down, heh."
