Hue, back in my day, it was actually just 5 DMs, but i s'pose the term can have evolved. I mean, 5 DM boomhits do exist (and let's not even get into pusga's record boomhit), would they have counted as one hit madmans? :v
I actually like that definition though, madman replays are basically the Toribash equivalent of HOKUTO HYAKURETSU KEN ATATATATATATATATA anyways. Also, i'm pretty sure "ukebashing" is just the term used for replays where you uh... Bash uke. I mean, with the advent of tricking replays and the likes, it makes sense to have a distinction. :U
