Oh Jerome, what on earth were you thinking?
Germany looked to be on course to book a place in the semi-finals of Euro 2016 after they took the lead against Italy this evening.
Mesut Ozil gave his side the lead midway through the second half, and at that point the Germans looked to be cruising to victory.
However, little more than 10 minutes after Ozil's opener, Boateng gave Italy a lifeline with a frankly ridiculous handball in the box that gave the ref no choice but to award a penalty that Leonardo Bonucci promptly dispatched.
Inevitably, the good folk of the internet were on hand to mock him mercilessly, and you can check out the best of the reaction below.
Of course, Boateng is no stranger to being mocked online - he was the subject of thousands of memes when he was left on his backside by Lionel Messi in Bayern Munich's Champions League defeat against Barcelona last year.
Reigning World Cup holders Germany have a surprisingly terrible record against Italy, and haven't beaten them in their last eight meetings at major tournaments.
However Antonio Conte is without Roma midfielder Daniele de Rossi, who picked up an injury in the Azzurri's win against Spain, while his replacement, Thiago Motta, is also absent.
Marco Veratti, Italy's starting midfield lynchpin, has missed the tournament because of injury - but his absence certainly doesn't seem to have affected them so far.
