The action of sucking flatulence back whence it came.
I really needed to fart while in that meeting so I had to traf it for release once I was outside.

fart spelled backwards. The occurrence of partly a passage of flatus and partly solid or liquid matter into the garment nearest the anus.
A traf occurs when the gas/shit separator fails.

When a combination of people's farts mix, and then, for some strange reason, you find anything funny and laugh out loud.
If you were sat in the staffroom at work and you all start farting and everything just bcomes funny and you don't know why, this would be traf.
