I totally agree, on the projection of the others and on the moderation! We dont often drink during the week but do enjoy a few of something or other at the weekend. I feel pretty good for it. Its major relaxing.
We have the same saying over here. I suspect it was probably copied. It was always the cry in School. As soon as someone mentioned something whiffy... boom! He who smelt it... dealt it! :OD
I definitely wouldn't worry about it if I were you. Lol, flatulence is the universal language and crosses all cultural boundaries.
I only had a little giggle. It was a microsecond!
Flatulence is the great leveler 😀
