Where your mouth and arsehole are in relation to your centre of mass would determine whether you get a lateral or rotational movement
Also you'd need to expose your mouth and arse to space, otherwise you'd just be expelling gases into your spacesuit and not generating any motion. This exposure might prove lethal quite quickly, as your entire oesophagus, rectum and intestines are exposed to the sheer cold of vacuum, turning you into a frozen farty meat lolly. Kind of like your mum.

Best TED talk ever

I didn't account above for the possibility of being in an orbital craft such as the ISS, where you'd be in freefall orbit which seems like zero gravity from your perspective, despite gravity still being about 99% as strong as it is on Earth's surface.
If you guff and burp simultaneously in a fully enclosed, pressurised and oxygenated craft, your rotation or lateral movement relative to the craft would still be dependent on your centre of mass and where your mouth and arse are, but you wouldn't freeze. You'd probably make yourself unpopular though - unless you're in space on your own, which is where you belong, you bellend.

I will now take questions from the audience.

I can provide the most effective answer to that by shitting directly into your ear.
