Psi-bombing

A sigh so loud it can be heard 10ft away, affecting the mood of those nearby. Commonly occurs in high-stress jobs (e.g. IT or management) from overly negative people frequently throughout the day, so much so that it starts affecting their normal breathing pattern.

*Co-worker sighs audibly several times*
Me, "Dude could you stop Psi-bombing me and just breathe already?"
