Defined as a small, average man who often wears sleevless shirts and over gels his hair in an attempt to look cooler, and often carries around an item in an attempt to look more cool (i.e. a guitar that he cannot play, etc.)
It is often an insult to be called a "Larry-Cooper".
"Oh look, there's a Larry-Cooper!" *followed by laughter*
"Your mom is Larry-Cooper!"
"He totally pulled a Larry-Cooper!"
"I hope that new kid isn't a Larry-Cooper."
"OMG. I broke up with my ex because he went Larry-Cooper on me."
