Hi, What is the meaning of frenzied end in the following text?

At last year's auction, Flint had valiantly hung on to the frenzied end and walked away with a $6 million artistic waste.......


anonymousthe frenzied end

The end of the auction where many people were bidding furiously against each other.

The usual expression is "bitter end". The writer has substituted "frenzied", rather irrelevantly as it relates to bitterness, I suppose to mean that in the last moments of the auction, the bidding was rapid and surprising, a frenzy.

Thanks for both replies.
