Back when I was at school - and right up to this very day - there is a rule of begging forgiveness for a flatulent outburst.

Trump - excuse me
Burp - pardon me

I still look at people askance if they get this wrong. Come on - its not fucking difficult.

[log]If you do find it difficult to remember, simply follow this rhyme. "Excuse me poos" (because farts and poos are the solid and gaseous states of faecal matter)and "Pardon your hard-on". For this second phrase, you need to imagine that you have just burped onto a man's erection. If you don't want to imagine burping onto a man's nice erection, try "pardon my lardon", and imagine that you have burped up a bit of bacon into a priest's beard. Actually, this one makes more sense. Forget about the dicks.[/log]
