Sexy in a Brother Kind of Way 

A type of sexiness found in men. Similar to "the boy next door" or the sexiness of a male friend that you're really close with. Basically, this type of sexiness applies best to Jake Gyllenhaal.

Tessa- Jake Gyllenhaal is sexy in a brother kind of way.
Dakota/ Alex- YES MA'AM!

Cornball Brother 

A man of Black/African descent who does not support nor does he identify with the Black/African-American community. Such an individual is usually looked down upon by African-Americans and considered to be a sell out, not for being educated or well mannered as African-American celebrities such as Will Smith and Denzel Washington are NOT considered "cornball brothers", but rather for essentially shunning their heritage and all those associated with it.

RG3 is a cornball brother.
