One Man Party also known as OMP is a term coined by visionary/creative genius Nick R. Walker. A graphic designer/writer/illustrator/musician/puppeteer/horticulturist,and also a huge fucking loner based out of Pittsburgh, PA. verb. When one "omps" they proceed to participate in "events" that are executed in a singular peerless fashion. To omp-omping-omped-omped out. ®
Dude, I OMPed like a fucking rockstar last night!! I don't remember anything other than building a fire in my front yard at 3am, talking to some ghosts, and running around making meerkate noises.
