Never seen such case before!!!....I think it depends on the definition of the words "cool" and "nerdy",the people interests as well.
"Cool" means that guy must be a bishounen,right?Or not?Or he is out-going,smart,good at sports,...etc
Same goes for the word "nerdy".
Anyway,in my opinion,what important is not the look but the personality of the people.But that's rare, many people judge others by how they look so....who knows?
