A state of mind when you don't think and buy a totally overpriced
thing that can be done
better or cheaper in x way. You don't listen to your
friends' advice and you go purely according to your intuition and then you defend your decision even though you know it's wrong.

friends, but because they weren't quick enough, he bought a standing ticket for
300 euros, even though he could have waited a little longer and bought a ticket for 110 euros with his
friends. Classical Vašek thing
