desert1p, You are 100% correct - a foul is not always JUST a foul - certain, more egregious fouls come under the heading of unsportsmanlike conduct and dictate a harsher penalty than loss of one ball or one point. Here's a possible example of that type of foul that transpired at the DCC last year, and which I witnessed....
Piggybanks was playing Shawn Putnam in a tournament one pocket match........There were several balls lying randomly spread out down table in between both of their pockets, meaning that balls were there to be run for whoever got a shot first..........Shawn tried a straight back and missed, also narrowly missing a scratch in the bottom left corner pocket, and the cue ball ended up sitting in the jaws of the pocket...........Piggy was not corner-hooked by about 1/2 inch - Piggy did not have a good safety shot, and he didn't want to bet the whole game by shooting a long shot from the jaws...........Now, I have been in this situation many times, as I'm sure most of the one pocket players on here have been - one shot option in this spot is to very softly/delicately stroke the cue ball, having it just travel that 1/2 inch, resulting in corner-hooking your opponent...........Well, I guess Piggy didn't trust his soft-touch-stroke ^_^ so instead he just firmly, jammed-stroked the cue ball into the corner-hook........Well, Shawn came flying out of his chair, ballistic - telling Piggy that's an illegal shot and calling for Scott Smith - you think Shawn considered that a normal, garden-variety foul ? - not hardly.
And besides, all sports have fouls, and then they have MEGA-FOULS, for example:
Boxing.....In a clinch, you can nibble a little on your opponents ear and maybe just get a point subtracted ^_^ - But if you bite your opponents ear completely off, you're disqualified - and what the hell is our old champ Mike doing these days anyway ?
Baseball.....Tell the umpire he's blind after calling you out, and just get a reprimand - call him a blind motherfu.... and you're out of the game.......and we can cite examples of fouls vs. MEGA-FOULS in every other sport in existence, from golf, to horse racing, to the olympic games.
