trail one off
to get up from one's chair and walk around with the express purpose of letting a fart rip. This has a few benefits; (1) the smell cannot be easily attributed to the emitter (2) the smell will distribute across a wider area, and dissipate more quickly (3) one's own work area will not become a miasma of the stench of one's own arse (4) it could even be coupled with a quick trip to The Gent's for a hasty kiss from Neptune herself.
I had Jalapeño's in my sandwiches for lunch; time to trail one off before the fog gets too thick
