look up any word, like smh:
 
1.
A term used to characterize most bosses of the King of Fighters series (and other SNK fighting games).

It is characterized by
1. The characters having unusually high damage and priority in their moves.

2. Annoying, repetitive A.I. which reads the input of the opponent's moves in advance.

3. Can only be beaten with the use of stupid patterns (most of the time).
Damn man, Rugal has a really bad case of SNK boss syndrome.
