A tumblr account is open to anybody to send in their photos of themselves re-enacting classic Courtois saves in their homes, workplaces and anywhere else they fancy.
The definition of Thibauting is: 'emulating a classic Thibaut Courtois goalkeeping save in any random location'.
It is pronounced 'tee-boh-ing', after the craze started in honour of Broncos quarterback Tim Tebow.
Explaining the homage, the tumblr account manager explains: "We are Thibaut fans. You are probably a Thibaut fan. This makes us all friends.
"Friends share things, and here, we share our love for Thibaut by submitting our very own homages to the glorious goalkeeping of Thibaut Courtois.
"Thibauting is our way of saying, 'Hey man, your skills are quite superior,' or 'I got mad love for you, bro.'
"If you share our mad love for Thibaut, why not submit your own classic save here?"
