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.
Pressing one button repetitively in order to beat an opponent. Usually noobs do this because they don't know how to do anything else. This term was popularized by the game Tekken where one could just press punch the entire fight and win as they wouldn't be able to respond.
GREATEST FIGHTING GAME EVER
unmatched depth in gameplay. Probably take 10 years to master all the layers of depth within just tekken 3. Button mashing aint gonna get you far on this one. The fighting system isnt based on over the top infinities, shooting fireballs, or over powered moves. Yet it is still so fun.
