Pumper Stoked 

The act of being pumped up and stoked about something at the same time.

After landing the sick 900 Stalefish in the halfpipe I was super Pumper Stoked about it!

pumper stumper 

The act of two people taking simultaneous shits but not allowing their feces to drop. They must both touch their shits together.

An imminent rectal evacuation was necessary after a meal at Denny's. With only one toilet available, a jolly good time was had with a pumper stumper to contest priority to the shitter.

Pumper Slug 

A real firefighter. The only kind that ride Pumpers (engines) and put out the fires. Not a truckie.

Have you ever seen a truckie actually put out a fire? No, because that's the pumper slugs job. The truckies just stand around flexing for the camera.

Pumper's Doom 

When you are trying to squeeze your fingers together but you can't. Mainly caused by excessive masturbation combined with cycling into work.

'God damn my hands are hurting, I can't squeeze my fingers together, my girlfriend (who is a physio) tells me it's "Pumper's Doom"...'
