You need to fart. what do you do?

Fart slowly and quietly.

I'd stand up without saying a word, raise my leg in the air, raise my fist in the air as well, and then simultaneously fart and pull down my fist at the same time so it's in time with my fart. Then sit back down nonchalantly as if nothing happened.

Oh and then just for shits and giggles I might audaciously raise my hand and ask the teacher if I can go to the toilet, so I can giggle and shit.

fart it out loud and look around laughing uncontrollably

Lay an angry fart and don't say excuse me, just keep walking.

Ask for teacher's permission and fart out loud so that whole class can hear it.

SBD.

Explode.

Depends on where and with.

Fart and announce that there's more room outside than there is in.

*I used to do this. It works well.

Blame it on the thunder.

I've had many experiences where I had to break i- I mean, "visit", ahem, some places. Of course, usually, the "owners" would be around. And guys in my line of work need to keep dead quiet. Thanks to years of this, Tony Lasagna can hold as many farts as he can. But believe me, just don't pile'em up too much. They can pile as high up to your throat if ya don't let'em out eventually. Trust me, it ain't a good look. Don't even get me started with the smell.

Fart and blame it on the fat kid nearby, or on the dorkiest kid around... Works like a charm.

I don't hesitate to fart, whether alone or in public. They're loud, but glorious.

Put a silencer on it.

If you're in a classroom then don't fart because girls. If you're with your friends then go up to them and fart on them 4 the lulz.
