Similar to a bromance, but a bromodachi is a purely platonic relationship between two males. A combination of the word "brother" and "tomodachi", the Japanese word for "friend".
"Al and Abe don't have a bromance, but a bromodachi. They've known each other for years, and Abe introduced Al to his longtime girlfriend. In fact, Abe will be the best man at Al's wedding next year."
