when a wrestler gets a hot tag and starts doing close lines and the sequence to signature before setting up finisher what is it called?

That’s usually called a hot tag comeback or just a hot tag sequence in tag-team wrestling. The crowd-pleasing run of strikes, clotheslines, signature moves, and then the finisher is the classic payoff after the fresh partner gets the tag.

Common wording

• Hot tag : the tag itself, especially when the fresher wrestler comes in with momentum.

• Comeback sequence : the run of offense that follows, often including clotheslines and big signature spots before the finisher.

• Babyface fire-up : a more general term for that energized burst of offense.

How wrestlers might say it

People in the business might describe it as:

• “a hot tag comeback.”
• “the house-clearing sequence.”
• “the finishing stretch after the hot tag.”

If you mean the exact in-ring structure, hot tag sequence is probably the cleanest answer.
