What mean たまらない in this sentence


After giving a ride to a girl, a character says: 放課後 迎えに来っからよ

Then the girl says: 冗談！ お顔と相談ね！ ちょっとバイクに 乗せてもらったからってたまりませんわ！

I didn't understand the meaning of the たまりません. Could you explain me?

お返事、ありがとうございます




たまらない (or たまらん, たまんねー, etc.; literally "won't stay") is a fixed way to say
either of:

  * it's so bad that I cannot bear it; no way; unbearable; unreasonable; overwhelmed
  * it's so cool that I cannot hold it; irresistible

As always, the meaning depends on the context. In your situation, it's used in
the former sense. She's saying dating her after school is out of the question
and she is amazed/overwhelmed by such an unreasonable suggestion. (By the way,
this せんわ is a Kansai-ben sentence ender. Is she a kansai-ben speaker?)
