Weak is Strong or Strong is Weak
In its most simplistic form, this usually applies to novice players but frequently applies to pros as well. Basically, players like to be actors, and when they have a monster hand they tend to look disinterested. For example: "Oh, is it my turn to act" or "Oh I guess I will play these cards". Alternatively, a player increasing the level of his voice while raising the pot, and trying to look intimidating.. may be running a bluff.

exposed cardA card whose face has been deliberately or accidentally revealed to players normally not entitled to that information during the play of the game. Various games have different rules about how to handle this irregularity. Compare to "boxed card".U
expectation, expected value, EVSee expected value. Often used in poker to mean "profitability in the long run".U
Holding BreathOften, inexperienced players will hold their breath if they are bluffing.W
Chat revokedWhile not a subset of the rant, a small number of online players list "chat revoked" or something similar as their location due to the cardroom blocking their chat privileges for some prior immature or rude chat outburst. When you see one of these players who needs to tell you that their chat is revoked, you know you are dealing with an immature person. They are also more likely to tilt (though not necessarily, they could have had chat revoked for racist or misogynist talk). If most chat revoked players lose a pot in an ugly way, you KNOW they wish they could call their opponent an idiot or worse. The WANT to rant. They WANT to insult. They want to exacerbate the tilt impulses they are feeling. You can even push them further by saying something like "nice hand" to the winner. You should be able to see the steam coming out of the chat revoked player's icon.

redrawTo represent a hand is to play as if you hold it (whether you actually hold it or are bluffing).U
equityOne's mathematical expected value from the current deal, calculated by multiplying the amount of money in the pot by one's probability of winning. For example, if the pot currently contains $100, and you estimate that you have a one in four chance of winning it, then your equity in the pot is $25. If a split is possible, the equity also includes the probability of winning a split times the size of that split; for example, if the pot has $100, and you have a 1/4 chance of winning and a 1/5 chance of taking a $50 split, your equity is $25 + $10 = $35.U
buy-inThe minimum required amount of chips that must be "bought" to become involved in a game (or tournament). For example, a $4-$8 fixed limit game might require a player to buy at least $40 worth of chips. This is typically far less than an average player would expect to play with for any amount of time, but large enough that the player can play a number of hands without buying more, so the game isn't slowed down by constant chip-buying.U
