Leonard McCoy isn't an honest man, but he used to be better at faking it. He never expected leaving the wizarding community and starting over as someone else - in muggle Starfleet, of all places - to be easy; but until the five-year mission started, it was never quite this hard, either. SLASH
Jason Todd always assumed that someone would have to die to resolve his identity crisis. Fortunately for Gotham, that's all that went according to plan.
Or, five times McCoy's AU counterparts disparaged his masculinity, and that time he finally got revenge. Cracky, slashy silliness.
