'manly' is the definition.
(I've seen this before)

'scot with a useless house' is the wordplay.
'scot' becomes 'mac' (many Scottish surnames begin with Mac).
'with' is a charade indicator (letters next to each other).
'a useless house' becomes 'ho' (abbreviation for house. I am not sure about the 'useless' bit.).
'mac'+'ho'='MACHO'

Can you help me to learn more?

(Other definitions for macho that I've seen before include "Blokeish" , "Affectedly virile" , "Spiny lobster" , "Ultra-masculine" , "Typically tough (guy)" .)
