Here are some examples:
* "She won the lottery twice in a row." This means she won the lottery on two separate occasions, one immediately following the other.
* "He scored a goal twice in a row." This means he scored a goal in two consecutive games or matches.
* "I flipped a coin and got heads twice in a row." This means the coin landed on heads on two consecutive flips.
Essentially, "twice in a row" indicates that something has occurred twice, with no other event or action happening in between.
