MAN
i was playing in our local casino and slow played the nut flush and pushed all in on the river he called i imediately showed my cards saying ive the nuts this charater known as "bad beat" says "oh and thanks by the way for slow rolling" meaning slow playing i guess ok i kept quiet because i know the guy just lost a big enough pot against me but later on ive a big decision to make hes not involved in the hand and asks the dealer to call time he then makes some remarks and when on the river my opponent hits a lucky straight he stands up and points to it OH YA AND SHOUTS IT OUT .normally these guys dont bother me but for some reason i was really pissed off with him i felt like pounding his head in like ive got the long hair thing going myb he thinks im some sort of whimp or hippy but i used do boxing and hardcore sports in short i wud destroy him so do i ignore this and go bck plaaying as normal or calculate some witty remarks to send him off the deep end or option 2 ill be shaving my head go in and scare the life out of him and be nasty at the table give him some of his own medicine or 3 i know where he works and give him a good thumping irish style but one problem i have is that the guys life is miserable he works all week then blows it in the casino playing poker but god id love to bash him over the head advice or opinions about this type of person
