QB Marino
I believe the answer is:
dan
'qb marino' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dan that I've seen before include "Judo, karate level" , "Level of proficiency in Japanese martial arts" , "Skill level in judo" , "Expertise level in juso" , "An expert in throws" .)
