非标准术语（CO River Float Static）

This term is not a standard term in Texas Hold'em. 'CO' usually refers to the cutoff position to the right of the dealer, 'River' refers to the river betting round, 'Float' means calling with a weak hand on the flop or turn to bluff on a later street, and 'Static' may indicate static or unchanging. However, combining these words together does not have a universally recognized precise definition; it may be a term coined by a specific player or small group. It is recommended to understand through context or directly ask the user to clarify their intent.
