A "pet name" of sorts, used to describe step brothers. Steppy brothers, however, is much more of an affectionate term, possibly coined by one of the steppy brother's close friends or family (family being not the other steppy brother of course) to highlight the deep bond these two males truly share.
Brennan and Dale are just stepbrothers, while James and Elliot are truly steppy brothers.
