Referring to the earlier Tekken days (PS1 and PS2) when their hair was jagged and unkempt, much like when one rolls out of
bed. This can be
seen done on purpose by pompous hipsters.
Rushing out the
door after waking up from a nyquil coma, Nick was late for
work and did not have
time to tame his Tekken Head. There was no hope in fixing his Tekken Head and he was later fired for his unkempt appearance.
