loud and nonlethal

The opposite of "silent but deadly". A loud fart, with no stink.

A very audible fart, with no smell involved.

"Yeah, I blasted out a loud but nonleathal in the movie theatre. Everyone heard me, but at least they werent mustard gassed". Loud and nonlethal, they didnt die from my gas, only from my embarassment, by laughing too hard.
