The psychological sequence that involves an individual who only displays one barefoot (and another foot that has a sock or any foot covering on), especially to record a video or take pictures for sexual gratification or attention. This term is specifically focused on individuals who prefer having only one barefoot shown rather than both barefeet at the same time.
Some videos on YouTube demonstrate "only one sock on, one sock off" conditioning to sexually attract some individuals (predominantly males) who prefer over some videos that show both barefeet at the same time.

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.
