What does banana bunch mean?

banana bunch meaning in Urban Dictionary

In American soccer, that is an offensive formation that is (obviously) used exclusively by Pittsburgh groups, especially the Pittsburgh Steelers. The expression seems to have been made-up by radio personality/sports broadcaster Bill Hillgrove, who perceives this formation to stay use constantly throughout every Steelers unpleasant drive. No one is actually certain what he is discussing, but most concur that it's enjoyable.
