I know this is highly unlikely, but the sentance says "intendss to teach someone a well deserved lesson". It may not even be a fight.

From what we've seen in RWBY, the characters are not just mindless fighting machines, they act like normal teenagers facing school problems like bullying and foodfights. Perhaps Yang simply intends to get back at somebody in a more childish way. Maybe like a major prank on someone? (and knowing Yang's personality, its highly possible)
