flip a Boolean variable vs complement a Boolean variable

Both phrases are correct, but they have slightly different meanings. 'Flip a boolean variable' means to change the value of a boolean variable from true to false or vice versa. On the other hand, 'complement a boolean variable' means to apply the logical NOT operation to the variable, changing true to false and false to true.
