Does anyone know how to throw up/vomit/purge?

im not gonna lie and say "oh i swallowed something bad" or something like "i feel sick and need to get it over with" ok. Just tell me my answer straight forward and to the point so you and i can get on with our lives and you can get your points. Oh and no lectures PLEASE i know everything trust me i did a whole fcking report on ALL types of Eating Disorders and did reasearch on every single one of them so please no dont waste my time cause i wont read them. And plus im not even trying to loose weight so it doesnt even matter
