I was in fitness and we were doing sit ups, i could feel one brewing so I had to stop, but the teacher who was holding my feet down made me do them faster, a little one went off but was ok, so i carried on and boom, a massive ripper come out, the whole hall could hear it, 40 people, so embarrassing, so i turned around and just layed on my stomach with my hands covering my face, this was only like 3 weeks ago as well haha..
