Musa vs Akpos

After writing a maths examination, a fight ensued between Musa and Akpos. Classmates gathered around to watch the the two students exhibit their boxing skills. A teacher separated them and asked them why them were fighting...

AKPOS: This idiot copied me during the maths exam!

MUSA: Copy? Hes lying! I didnt write anything! My answer booklet was blank before I submitted!

AKPOS: You copied my blank answers! Because I didnt write anything on my answer booklet too before I submitted!

One word for Akpos?
