when applied to Dominican Poker rooms, this would usually mean colluding between Dominican players or friends at the expense of foreign players/new players in many different ways, too many to mention, some planned some just opportunistic.
Other shenigans are buying in for small amounts, going all-in, over and over and over again, to try to make a big stack out of a small stack- killing the game due to repeated chip counts for side pots and the fact that good players dont like this. The minimum buy-ins should reflect the blinds but they never do in the DR.
cussing the table, taking too long, folding out of turn, smashing the hand on the tabe, yelling really loud, arguing over ridiculous subjects due to saving face, talking on the cell phone in the middle of a hand, the list goes on and on..
