In poker, there are five positions: caller, preflop raiser, flopped raiser, late position player (LOP), and button. The caller is the first player to act in a hand and make a bet. The preflop raiser is the player who makes the first bet before any cards are dealt. The flopped raiser is the player who raises the preflop bet after seeing a flop.
The LOP is the last player to act in a hand and make a bet. The button is the player who is seated in front of the dealer button.
