"It's OK if people laugh a little – there'll be a few YouTube clips and a few memes," Hradecky predicted after his side went second in the German league after a 2-1 win at Arminia Bielefeld.
Leverkusen was 1-0 up thanks to an early Leon Bailey goal when Hradecky's howler just after the break handed Bielefeld an equaliser.
With no opponent near him, Hradecky watched in horror as a clearance bobbled slightly before spinning off his boot and into the goal behind him.
However, his blushes were spared when Aleksandar Dragovic stabbed home a late winner.
The relieved 30-year-old Finland goalkeeper hugged Dragovic in gratitude at the final whistle.
"The team and Dragovic helped me out - my beer will taste good after this," a relieved Hradecky added.
It was a curious away win for Leverkusen, which lost both its twin defenders Sven and Lars Bender to injury.
Leverkusen captain Lars was replaced with deep bruising for the start of the second-half.
Sven was replaced soon after by match-winner Dragovic when he was injured in a challenge.
