So he is lending his support to the latest phase of the Premier League's No Room For Racism initiative by opening up about his experiences so that other children can better understand what racist abuse is when it happens and the harm it can do to people.
"I was 12-ish," Origi said of the incident in Belgium. "We had a game away and one of the parents racially abused me because I was having a good game basically and I was playing against his son."
"It was horrible. I wouldn't cry much but then I broke down. I couldn't play any more because it hurt me, right to the core."
"We all come together and speak the language of football and that's what makes it so beautiful"
Origi was the only black player in the team and although he remembers that his team-mates were compassionate, he also recalls that they struggled to know what to say.
"We had a bus ride and it's quite far, so coming back I was speaking to them about it and they would ask me questions," he says. "It was confusing.
"I felt the compassion but they didn't really know what to do or what to say. I was just waiting to go and speak with my parents.
"The coach was speechless, he didn't know what to say. Obviously he defended me but he found it weird."
Origi now plays for a Liverpool side which is more diverse than his boys' team and he sees the positive impact that the mix of cultures and races can have on one another.
"For me, it's special," he says. "When I go to the dressing room, you see the Brazilians, you see people from Guinea, you see English people. You see everything and it comes together in one dressing room.
"The interaction is very funny. I can see the different types of humour and the different types of expressing themselves and clothing.
"And we all come together and speak the language of football and that's what makes it so beautiful."
Origi was speaking as part of a series of free bespoke resources created for the Premier League Primary Stars programme, which aim to stimulate classroom discussions on diversity.
